My Story

I just recently found out that my beloved PitBull named Kaos has or had cancer. If you are a dog owner who treats him like a member of the family you can imagine how scary and traumatic for both you and your dog it can be to think he may be sick.

I noticed that Kaos had a small bump under the skin on his lower back leg almost on his foot. I thought no big deal and figured it was a bug bite. As the days and weeks went by I was getting more nervous about the bump cause it was still there not changing just sitting there. Then all of the sudden like seriously overnight the bump had turned into this nasty red bubble looking thing. It took a month before it started to change and look serious. Before that it was not red and didn't have the bubble yet.

So I made the appointment and the next day he went to the vet. Vet says well I don't know what it is for sure until we get it out of his leg and send it off to be tested. I thought either way it was not supposed to be there so we might as well take it off now. My boyfriend kept telling me maybe we should get a 2nd opinion. I thought the sooner the better. So we had it removed that day. The vet told me to come back in 30 minutes and it would be gone and Kaos could go home. He would sedate him and he would not feel a thing.

This was the first time I had ever left my dog in a strange new place all alone with some strange man poking and proding at him and I felt terrible but had to do it so I did. When I picked him up he seems fine and has a bandage around his leg.

After we got home I looked at his leg and was upset about how big of a cut the vet had left. He even had 4 or 5 stitches. It looked awful and still does. A week later vet calls with results and tells me it was a mast cell tumor and it was a stage 2 but it was a very nasty and aggressive type that often spread to the lymph nodes and we should keep watching Kaos and checking him to make sure no more bumps came up. Then told me to give him 25 milligrams of benadryl every day.

Anyway the whole week of waiting was hard. I just new my dog was going to die and I cried and cried. I never imagined I would be bawling over a dog like a big cry baby.....but I was. He is the biggest soiled brat but I still love him.

. When he does die I am going to have him stuffed so he will be with me forever.......LOL Just kidding. Im not that crazy. But I do love him a lot.

I am not sure if Kaos is going to get better and stay that way. He doesn't act sick and is still very playful so I am hoping he will be okay and be around for many years to come. He is 5 years old now.

Signs of Tumors And Grade

Check your dog all over like you are petting him and look for any small bumps that were not there before. If the bump changes in any way take him in to get checked out.

The mast cell tumor causes histamine to be released into the blood and may cause your dog to vomit for no apparent reason.

They can also cause the blood pressure to drop or to have a fast heartbeat.

Mast cell tumors are graded according to how serious they are and the potential it has to kill the animal.

Grade I being benign, Grade III being malignant, and Grade II having some ability to go either way.

After removing the tumor depending on how severe it is your vet may prescribe an antihistamine medication or prednisone. Chemotherapy and or radiation may also be prescribed. Chemo and radiation are very expensive but can prolong life for a few years depending on the grade and stage of tumor.

Don't assume the worse if you think your dog may have cancer. If you find out that he does then do what you can to make sure he has a quality life for the rest of the time he has with you. Many times after removing the tumor a dog will be just fine and live a long life and be cured with no returning tumors.

I don't think anyone should take this article serious as a legit source of correct information considering the female writing it misspelled over 10 words and used phrases "like, seriously"...ok kid

Melissa on June 15, 2012:

I am very concerned with my little guy I thinks it a bump jjust like that and I am hoping I can email you a picture because I love him very much but I think vets need you to pay upfront and that is the only rreason I have not had it done, I love my Ranger he is white and fawn with. Big bubbly on his leg above his paw. Is the only thing to do to take him to the vet or can I do something at home?

aisling murray on May 27, 2012:

my dog has had a 11 puppies they are 1 week old today but when i went to check on them the last pup has a large bubble around it's front paw what can i do for the puppy?? And my dog that had them doesn't really treat it any better than the rest of the puppies! Please help me or tell me what it is and what to do about the pup that has the bubble around it's front paw! Please help!!

barkinglulu on May 22, 2012:

ugh. My rescued pit bull, Lulu, had stage 2 cancer on her neck last summer. The vet was shocked that it was malignant because she was only 6 years old. After removal, they were even more shocked to find out it was stage 2. At that time, they informed me that even though they had removed the entire tumor, it was likely to return at some point and metastasize.

Fast forward to today. She has 2 small tumors; each one about 2 inches down her rib cage from her spine. She is acting very lethargic and can't seem to hold her pee or poo for very long. We left the house today for an hour and she had 2 accidents.

I am a poor, single mom and as much as I adore this dog, it is hard to shell out several thousand dollars less than a year after the last surgery. I am quite devastated. I am contemplating a fundraising drive to save Lulu for my daughter. My daughter and my dog are inseparable. I am just so dang sad about sick over this. I am not really sure what kind of advice I am looking for. Maybe I am searching for some hope. What are her chances? If we go through all of this, will she just get more cancer? Will she die anyways? This dog is my first baby.

m-c on May 20, 2012:

my dog is only 10 moth old and we found a lump today on her right hand side. we are taking her to the vets tomorrow. in the article it says to prolong their life for another few years, it has scared me and i don't want to lose her at such an early age. my parents had the exact same breed of dog i had (Labrador) and he had a tumor in his stomach. he was soo weak that he hardly came around from the local anesthetic, he was 11 years old. the vets felt it was thew best thing to do

Lea Ann on May 20, 2012:

I have a 10yr old rotti mix (Reiley) We had a health scare with him, when he was about a year old. The vet said it was cancer( I now how to go home and tell my 3 young girls and my husband that Reiley had cancer) We had just lost our 11 yr old boxer to cancer prior to getting Reiley. Heartbreaking to say the least. Reiley had to stay over night only to be followed with a phone call in the morning that it WASN'T cancer. I tyhen went and got a second opinion. It wasn't cancer.Long story short it was a food allergy or so they thought. Got rid of his plastic bowl changed to steel put him on Iams lamb & far so good. He has always had skin issues. Now at 10 I do know he does have cancer. Lumps & bumps everywhere, itches all the time. Still eats fine but the poor guy his constant itching is I am sure driving him crazy. He still plays and eveything else. I am going to try the Benadryl should I also do the Tagament and if so how much. He ways about 65 70 lbs.....Thanks

hi my name is ruth and i have a 2 year old beagle male and he has a kind of a pimple i would like to know what is that im worrying for my dog.=(

Bonni on May 06, 2012:

Yesterday, May 5 2012, I noticed a small bump on my puppy's leg. Sunny is a purebred yellow lab, and I fear the worst. She turned one year the first of may, so if she has cancer it really is not fair. I am hoping I am just paranoid. In 2009, I lost my beloved Athena, another yellow lab, to cancer growing in her leg. The only thing we could do was AMPUTATE! But when she was spayed as a puppy, she feel out of the truck and her hip wasn't it's strongest, so we couldn't force her to suffer. We lost her 4 days before her 12th birthday. :'( And now I am terrified I will lose my Sunny because of cancer again.

And now I can't stop crying; until now I didn't dare put my fear to words, but now it seems even

more real and heartbreaking.

Tell me, is it bad Sunny keeps trying to bite her leg near the bump?

Mary on April 29, 2012:

Rubber band not to tight and not to loose, cuts the blood supply off to the tumor which feeds on the blood..Will eventually fall off.Have to do this before it gets to big...Of course if you can afford the vet bill by all means but if you have no other resource what are your choices????

Dayle on April 06, 2012:

My baby girl Abraxas has a mass on her back foot pad. They gave her antibiotics to treat the infection from her licking it. That was a week ago. Her paw looks the same. Two days ago, I noticed she was licking another paw pad. She has another small growth on front pad too. The vet did a biapsy on her first pad but they are not sure what it is. The vet wants to remove the masses and have them tested again. She is 12yrs old and the sweetest dog ever. It would break my heart if she has cancer. I have read the previous comments and I know to have faith and not give up. Please wish us luck.

Becky on March 27, 2012:

:( .. I took my Abbeylee to the Vet this morning to have surgery on one of her breast on her left side... I never noticed her breast being swollen but one morning one of them was hanging really low... I laid her down on her side to look at it ,it was so imflammed i know it had to have been hurting her... but she never seemed any different until that one morning... I called the Vet that same day and took her that afternoon..They told me it looked like a Mammy Tumor..She has been gone all day, I called to go pick her up , and they said they are keeping her another night.. The nurse told me the Vet said it looked liked cancer but i could send it off to be sure if i wanted to..And of course i will... Im so sad, I miss my Abbeylee...Ive been crying ever sense i took her...:(It is weighing so hard on my mind that im gonna lose her...I cant even think of anything else... She is a gray and white Siberian Huskey 6 years old with 2 blue eyes like mine...She is so beautiful... I love her so... I cant imagine what my life would be without her... She has helped me in my sorrow times and has always been my best friend... If who ever reads this... Please say a prayer for my Abbeylee...Thank you... I will keep all the sick loved ones in my prayers as i know you love yours... God Bless..

My 13yr old dog houston whom I have had since I was 4 may have a cancerous tumor. I cant explain how I feel.

vanessa on March 21, 2012:

I have a 14 year old rottie mix and his name is rocky.Last month he had a tumor removed from his underside, close to his penis. The vet let me believe it was a fatty tumor and 2 weeks later behind his front leg a tumor filled loose skin and was super aggressive. The vet wanted another $800 to do another surgery. I went to another vet for a 2nd opinon and she put rocky on prednisone and benedryl. It has shrunk a lot but I don't know what to do. I think he keeps losing weight. His collar keeps getting looser and I hugged him a while ago and his bones on the side of his skull are really sticking out at his eyes. I am soooooo scared my boy is going to die...I cry all the time. I love him sooo much!

shreya on March 21, 2012:

my dog is also having cancer how i can save her from cancer please tell me

amanda on March 12, 2012:

she made it! She is cancer free! The surgery went well yesterday! The vet said to come back in 6 months for a check up. I am so happy she OK. The best of luck to everyone!

amanda on March 11, 2012:

Oh man so I am not a lone. Friday was the day we found out my dog has the samething. I am terrified that tomorrow she won't be here. I've been an emotional wreck, trying very hard to think positive. Autumn is 12yrs old and she is a golden lab/golden retriever. She also has dieabete, I just hope and prey she will make it through. I love her.

Susan Schilling on March 11, 2012:

Pet's are our family. Please consider looking for a good Holistic Vet.

Someone recommended that to me 5 years ago, 6 vets, so much money, but the worst of it, were the un-nessasary suffering of our dogs and my desperation to have them helped. I learned the hard way, holistic vets are NOT witch doctors but rather have an additional degree. Even more important is they look for cause, not treat the symptoms. We lost a Rhodesian to Mast Cell, but made choices for her, that I am at peace with. First, we decided on one surgery. Then, let he eat holistic dog food and she loved spinach out of the can, no salt:) They gave her 6 months without treatments, she lived 7 more years. One thing to keep in mind during trauma with dogs. They do not show pain until it is really bad. In the wild, to show weakness could make them prey. They also do not understand, as we do, why they can't run or why they get sick and vomit. Do all you can to be good to them. We waited too long with our lab Ashton. He was in so much distress, it was a terrible lesson for me. I cried for months. Never will we do that for us. Hope this helps.

Dee on March 07, 2012:

I am sitting here with my staffy Mia. She has a few fluid lumps under her skin. This is worry some. The vet says that they are only fatty tissue but every week she seems to be getting a few more.

Why is that I hear a lot more about cancerous tumors today than i every have before. Is it in the food we feed them? I know here in Australia a huge article was written about a dog food company VIP pet foods. It stated in this newspaper article that they put huge amounts Pet food laced with dangerously high levels of sulphur dioxode, tests reveal

This article was most upsetting and also very scary as to what we are feeding ours animals.

sue on February 28, 2012:

My beautiful girl Rottie Bonnie had a lump removed from her chest last week which has been diagnosed as a mass cell tumour grade 3. We are seeing a cancer specialist this thurday.. We lost our other Rottie 2 years ago to cancer, he was also 8 years old.. we don't know if they can do anything as grade 3 is the most aggressive kind.. our hearts are broken......

Dustin on February 13, 2012:

Hi, my dog has a little red bump on her stomach, she is 6 and ive just noticed the bump recently. she is a boxer her name is Lady, and i was just wondering what it could be. And she never licks it or messes with it.

roger on February 04, 2012:

thanks for the posts I found something similar on my 10 yr old pitbull today and will be bringing her to the vets monday. wish me luck.

stephanie on February 04, 2012:

my dog has got a lump on belly she is 6 years old and a miniture schnaourzier she dose not have a red lump it has just appeared im am unsure dose anyone know what it is?

MileHighFish on January 30, 2012:

Thanks for the article! In reading the comments, there are many I can relate to. Kasieg, I will be praying for you but it is important to remember a diagnosis of a mast cell tumor is not a death sentence and regardless you need to enjoy the time you do share with your dog:) My lab/retriever mix, Bailey, was diagnosed with a mast cell tumor in August of 2011. It was on his back towards his rear end and the surgeon was able to remove it with wide margins. Lab results came back fairly good. Low grade 2 with a low mitotic index. He recovered quickly and all was well. Last week while cleaning his ears, I noticed a small bump on the flap of one of his ears. Took him in to have it checked and it turned out to be another mast cell tumor... Hated to hear that and keeping my fingers crossed it isn't bad. He is in surgery as we speak to have it removed and taking it one day at a time. Enjoying all the moments I am able to share with him!:) As with all dogs, he is very special to me and my wife. At just under 5 years old, hoping he has many more years with us ahead of him but also realize that any form of cancer is not a good sign. Mast cell tumors are so unpredictable and not fully understood what or why the are caused. Keeping my fingers crossed for all those who go through this as I know the stress, anxiety, etc the entire process entails. I just try to heed my own words and not take any time with him for granted! Each and every moment is special:)

marie king on January 12, 2012:

How is Kaos now? Great article

kasieg on January 09, 2012:

usually my mom is against going to the vet because of the money cost but today she called and schedueled an appointment because she thinks my dog might have cancer because she has a tumor on her leg, im really scared though because we have had sable for almost 3 years and before that we had her for 2 ( we had to give her away when we moved but when we came back we got her again). i don't want another one of my dogs to die again because our perfect dog from the years in between died from a disease where he had a hole in his diaphram and all the things that were supposed to be in his stomach were in his chest and i dint even get to say goodbye so im really scared its gonna be so bad that when she brings her to get checked its gonna be so bad that they autimatically put her down and im super sacared so people can you please pray for my dog because i don't want her to die

cancerguru from Kentucky on January 08, 2012:

Thanks for sharing. Chemotherapy and radiation are so expensive for pets that no matter how much they feel a part of the family most average people cannot afford them. Here's hoping my dog stays healthy!

Dana on January 07, 2012:

Hi guys, I came across this site and just want to let u all, that there's still hope.Never ever give up!

My 4 year old French mastiff was diagnosed with soft tissue sarcoma in April 2011.She had it removed, but because it was lying on her spine it couldn't be removed all in once, so vet suggested another op(another €500).The cancer was the most aggressive one and there was big chance it'd grow back so we didn't want to let her suffer again and decided to try alternative way.I bought few herbs, but the lump started to grew back in July and in the end of September it was in size of rugby ball!

My dog had no energie, she didn't eat and lost a lot of weight. she was in so much pain that she couldn't move anymore and we really thought that few more days and we put her to sleep.It was breaking my heart to see her like this so after a lot of research I ordered all kind of herbs and exactly in that time one of our neighbour came to us that he's healer and he'll try to help us and I swear since then the lump started to shrink and now there is a bit left(it's jan 2012).

She put back all her weight and she's got so much energy that it's just unbelievable.Whoever sees her says it's just pure miracle.

Now I don't know what it was, the healing or herbs, I'd say both..

So never give up!

I took my German Shephard Hunny in to get fixed and to have a HUGE lump on her breast taken off and I just found out today (10/12/11) that they gave her no more then 18 months to live. they also said that it is a 50 50 weather it will come back or not. she will be 6 on Valentine's day. I was wondering if your 4 leged family member is still around and if so what did you do to help keep him around and/or if it didn't come back. and what were the odds the vet. told you that he had of it coming back. please email me at ASK_ME497@YAHOO.COM thanks and i hope that he is doing okay.

Kerry on October 11, 2011:

Hi, I hope that Kaos is still doing great! I just found out today that my dog has a cancerous tumor and I am really scared. I hope it gets removed and that that will be the end of it. Elmer is the best dog in the world and I have never been as close to another animal in all of my life. He is as close to perfect as possible. I wish we could get rid of this stupid disease!!!

m on October 08, 2011:

All tumors aside, it's nice to see so much love out there for pits. They are such wonderful, kind, devoted pets, and I can't imagine my life without my baby girl, Ella. She makes my world better, and I really hope people stop treating this breed so horribly.

Karen on August 31, 2011:

Hi Ashley,

I recently went through a very similar experience with my cat, Simba. His mast cell tumor was removed last week. I have to say, having insurance for all three of my "kids" has made situations such as this one less stressful than what they could have been.

I pay around $80/month for all three, but, in all honesty, I am, thanks to the policies, way in the black with respect to pet health care (I took out the insurance after losing a beloved cat quite unexpectedly to tachycardia; her last few days incurred me close to $3,000 in emergency care). It's something to keep in mind, especially for younger pets with few pre-existing conditions. What I have for them pays 90% minus $100 for any treatment needed on a 1st time illness (broadly defined; follow-up treatments on that illness included), 90% minus $100 for any treatment needed due to accidents, and $150/year towards wellness.

Best of luck with Kaos! I hope he heals well.



P.S. I went with 24 Pet Watch. My state's humane society pays for one month of insurance with this company on all new adoptees. The trust that this shelter continues to have in 24 Pet Watch helped me make my decision.

P.P.S. There has been quite a lot said in the above threads about natural treatments. I do not over-medicate and am all about preventative care. With that said, should my pet come down with something serious, he/she will be treated ... and pronto, with or without insurance and despite what I might have to sacrifice personally (I should clarify here that I am a graduate student with very few funds available for unplanned expenses).

P.P.P.S. I know I'm raving quite a bit about 24 Pet Watch, so I should also add that other than having taken out policies with the company, I am in no way associated with it or any other pet health care company.

Brian on August 03, 2011:

Thank you for your words. My beset friend Dre, a 9 year old pit bull, is going in for surgery tomorrow. He just fell asleep. He is in bed with his mama, cudding, just as sweet as he could be. I know it may just be the a simple procedure, but I am kinda freaking out. I guess it is the first sign of true age he has ever really shown. Yeah....he has gotten gray, but his pep and energy have remained. I love him. That energy will last forever.

Rebecca on May 28, 2011:

I'm siting here with Misha's head in my lap listening to her breathe. She is my baby. I have had her since she was a puppy. I drove 8 hours to pick her up in north Carolina. She is my baby amstaff. After being diagnosed with cancer last year she has lead a very active and happy life. 3 days ago we noticed her chest was somewhat swollen but we thought maybe she just pulled something. The next day it was twice as big ad she was having problems walking. I made an appointment for today, Saturday, but yesterday it got even worse so I made an emergency appointment for her yesterday. The vet took a biopsy and said her chest was filled with fluid and blood most likely from a tumor. Even though we won't know for sure until we get the results back I'm preparing myself for the worst. I can't imagine a day without her. She is my heart and best friend and has been with me through so much. I found her when I was 22 and I'm now 32. I feel like we've grown up together. She is still eating and giving kisses but sleeps mostly. All of it is breaking my heart into a billion pieces. I love her so much. I have been through some hard times in my life but NOTHING compares to this. I can't imagine what the next few days might bring. I think I might be in denial because I keep thinking maybe she will pull through somehow. I just trying to make her as happy as possible and show her so much love. I honestly don't know how I will get through this. I love her with all of my heart.

Johm on May 20, 2011:

Hello everyone don't now if this is still active last pose 3 weeks ago, I have been reading all of your storys and I also now think my pitball beagle mix may have this mast tumor like somne others a small bump for awhile and then in onday got big and today was all red. i made ap[pt for vet he goes mon. looked at some picsa and one or 2 look like it coulsd be same thing he has.

sunchild28 from Nigeria on April 28, 2011:

nice work you actually did in here.So much enjoyed your article because its quite interesting and educative.

Melissa on March 26, 2011:

Justus is a purebred English style Labrador. He has a great pedigree with no known illnesses in this pedigree. In January all of a sudden my daughter noticed a very large bulge on his side in the skin that connects his stomach to his leg. I took him to the vet and they did a needle aspiration which was inconclusive. Two days later he had the lump removed. The lump was bigger than a grapefruit and it appeared in only a week. Our vet thought it was suspicious so we decided to send it off for biopsy. It came back a grade 2 mast cell tumor but the cancer was confined to the inside of the tumor. No cancer cells were detected near or on the outside of the tumor. He turned 2 years old in February so he is still a baby. My vet said he has never seen this type of tumor in such a young dog. Until recently things seemed great but a few days ago he started to just lay around and today he vomited all his food. I am so worried that maybe the is more cancer inside him or that tumor spread and they didn't realize it. I am taking him back to the vet. If you have any advice I would gladly listen.

rob on March 19, 2011:

just found out my staff x boxer has cancer after finding two lumps on her stomach and her loosing so much weight. so upsetting she doesn't deserve this cancer is such a horrible disease, got vets again Tuesday to remove it and see if it has spread to her chest if it has they say it will be est to put her down :( im praying that it hasn't spread.

Mem on March 19, 2011:

Just got back from the vet my 3 1/2 year old boxer has a mast tumor and they say it's cancerous. Getting it removed next week, to get it biopsied and determine what stage it is in. We thought that it was just a bug bite or something.

Elena@LessIsHealthy on December 21, 2010:

Oh my God I hope your dog is fine now, no more tumor.....

Makaylah McSweeney on November 26, 2010:

All I can say is believe have faith he will go to doggy heaven

Evelyn on October 23, 2010:

My Buster had a mass cell tumour removed off of the back of his neck. The vet sent it off and it came back cancer stage 2. Now it has only been 2 months and he has another a little lower on his back. I know it is cancer. The vet put Buster on steroids and meds to put on it. I came home tonight and he is not acting right. He is very loving but tonight he is not, he is acting mean. I love him with all of my heart and do not know what to do.Can anyone tell me how long i have with him? Or is their a test that the vet can do to tell me how long his hads. He feels very hot tonight and his ears are red.

nyssa newnes on October 19, 2010:

i have a 8 year old boxer she has just had a mast cell lump removed from her foot,but they could not get it all out as its beetween her toes and have not got the space 2 get it all.they said its a grade 2,and the only way 2 get rid of it is to remove her leg!! i cant do that to her she would hate me for that!!she is going to go on steroids which should slow it down,but they could not give me any idea how long she has.she is fine in her self and would never let her suffer,just wanted an idea of how long she has,feel like its all i think about.

nataliek on October 09, 2010:

I feel really sad about your loving companion Kaos. I hope he recovers fully! I have a 90lb 15month old pit, Hugo that gets more love and attention than my kids (young adults now). I don't know that much about dog cancers but I realize there is so much to learn and so much we cannot control. Good luck, I hope everything turns out...I would feel the same.

Buznana on September 30, 2010:

What has it showed up to be Darryl? I Have a chiwawa that has gotten so fat she can hardly walk. Reading what you have experienced, maybe you can give me some insight on what to do for her. Part of me knows she has cancer, but the other part is going with the overweight answer. I have had several dogs (4 legged kids) die of cancer, she only eats people food, sleeps about 22 hrs a day, her stomach is so fat, she should only weigh 6 lbs, she weighs 11 lbs. She can't jump up on furniture now, I have a little ladder that I made for her out of pillows. I don't want her to suffer, but I think if I hake her to her vet, I don't think she will be coming home with me, and I'm just not ready for this. Do you have anymore knowledge on this subject, or anyone.....Thamks

Jenny on September 29, 2010:

I just found a bump on my dog's front leg. I cleaned it as per suggested by my doctor friend and waited two days. It still looks the same so I took him to his vet today. The vet said it looked like a tumor and asked it I wanted it removed and diagnosed. (Of course I do!) So the vet gave me an estimate, $330-$350 and took my dog right then and there. I was like, "Your taking him now?!" I couldn't help myself and tears welled up. I didn't have a chance to prepare myself. (my dog loves the vet so no preparation needed for him). I am expecting to pic him up this evening and I am super nervous and upset. He is a Lab, Rhodesian, probably Pit mix, 5 1/2yrs old. I've had him since he was a puppy and he is my only child. Please cross fingers for his recovery.

I hope that Kaos is still doing great? Can only imagine what you went through, I get manic if any of our babies develop lumps and bumps though so far we have been really lucky with them..

I heard of K9 immunity & transfactor help. Darryl, why don't you give it a try. I know the cheap site you can go to is If it doesn't hurt your dog, why not give it a try? Hope your dog will get well soon.

How is your dog? I hope hes doing well :)

Im sort of dog Rookie is i think either ten or 11 maybe 12 and he's a border colie springer spaniel mix. When we got him he we saw he had some bumps and as the year went on, they got worse. We got them all removed about 3 years ago but know he has several more. He goes through times every couple of months where he shakes and whines but when that isn't happening he loves to run and play. My vet hasn't said anyhting about cancer but i have absalutly no idea.

A Dog Cancer diagnosis is one of the scariest things you can face with your beloved companion. The ‘Family Pet’ is just that – A cherished member of the family. A diagnosis of cancer or other serious disease for him or her can be just as devastating as for any other member of the family. The thought of discarding or replacing our loved ones when they get sick is no more of an option than it would be for any other family member.

Check out the website for an herbal based formula called "neoplasene". It was developed by a Dr. Fox, a veterinarian. He only sells to vets, but he suggested that I print out the material and show it to my vet. to see if she would use it on my dog. Read the amazing case histories and check out the healing of many tumors in older dogs without surgery. In the meantime until I can find a vet to supervise this neoplasene treatment, I am dosing my 11 year old Weimeraner, "Dustin" with another product, calledsimply "Wart Cream" that contains bloodroot and chaparral and it seems to be draining the blood out of the tumor on his foreleg, so it is shrinking. I really need to find a doctor to oversee his treatment, because I am concerned that all cancerous tissue sloughs off and healthy tissue replaces it. This is exactly what is shown in the "Case Studies" section at the website for Buck Mountain Botanicals, or Buck Mountain Herbals. If you email them at, you will get a "form letter" reply telling you to call them to discuss your case. (If Dr. Fox himself answers be ready for a slightly cranky guy who loves animals but is not good with people, at least not me!) He claims to have treated 5000 animals successfully with neoplasene, so please check his site out!!

Awe. Those pictures are so sad. My bouvier had tumors all over. But not like that. Cancer is such a sad sickness. We are almost completely hopeless to fight back..

Hi Ashley,

How is Kaos doing? Hopefully all is well with him and he is recovering. Many blessings to you if he is still dealing with the cancer.

I have a similar situation going on right now with my adopted dog Cosmic. My husband and I live in Scotland and adopted our boy from Dogs Trust about 5 weeks ago. Cosmic is four and an ex racer greyhound. He is already the love of our lives and we are really distressed. His tumour was only slightly noticable when we brought him home. I thought it was just a skin tag or bug bite. It started to grow over the weeks, and he began licking/biting at it, so we called our vet. We took him in today and was told that it could be a MCT. We are getting it removed and biopsied next Tuesday to see what it actually is and what Grade it may fall under. He has been limping a bit on that leg, as well as limping on some of his other limbs. It is sporadic. He also has been eating at grass and vomiting, with some diarrhea. We are hoping and praying that all is well, but doggies can't tell us how they are feeling. He still runs, plays and has a good appetite. We just hope that we didn't adopt a seriously ill dog! I will be devastated!

We will post more as we learn more. Keep us in your thoughts and blessings that this won't turn into something serious.

My 9 year old Pit was diagnosed with a Grade 2 MCT in January. We had it removed and are doing the benadryl. In March, I found more and went to the oncologist. Testing on one showed no mast cells and another bump was diagnosed as a wart....well, the "wart" has tripled in size and texture! I am scared that its now a MCT.

I understand the emotions...our dogs (and cats for that matter) become our family. Its hard on the heart!!

Suzi on January 23, 2010:

My 10 year old pitbull was diagnosed with mast cell tumors 3 years ago. The first vet said that the location of the tumor meant that it was malignant and that she didn't have much longer.

The second vet ultrasounded her spleen and liver and found nothing. She biopsied the tumor and found it to be stage 2. She wanted to put my dog on chemotherapy and perform surgery. I couldn't afford that option.

I took my poor dog to a specialist-canine oncologist. He listened to our story and gave me a third alternative. He injected the two tumors with high doses of prednisone locally. He also put her on benadryl and an over the counter acid reflux medication. Within 5 months, the tumors shrank enough that he removed the tumors without having to put her under.

She has had no signs of return of that cancer and it has been two years. I am so glad that I didn't listen to the first vet. Best of luck to you all and I hope that you find a vet that is willing to work with you within your means.

I just found out my 4 yr old pit has stage 2 cancer.I just feel like dying.

Erin on January 06, 2010:

I'm so sorry to hear all these stories about your beloved dogs. My 2 year old poodle/terrier rescue from Puerto Rico,Nikki Sixx, has had spotting and bleeding problems since we adopted her in August. She had 2 surgeries to remove what our former vet told us was just a mass left over from her spaying in Puerto Rico. It seemed that no matter what the vet did these "masses" just kept coming back. I finally got fed up and took her to a different vet that just told us this "mass" was actually a tumor and could be cancerous. I'm completely heartbroken. This poor little girl has gone through so much suffering already. Our new vet said he's going to do his best to remove most of the tumor, but she may need radiation if some of the tumor can't be removed. Our former vet never once said the mass could be cancer. She goes in for surgery tomorrow morning and we're praying for her. She is an amazing dog and I don't know what we'd do with out her. I feel for anyone that has to go through something like this. I can't imagine life without Nikki.

Jacqueline Rowles on January 04, 2010:

OUr beloved pet, Kira a 9 yr. old german shepherd and pit bull went to the vets today because we found a mass over here one tooth over the weekend and in the day and a half since finding it it seems like it has grown. The vet says it is a tumor. The vet said that surgery to remove it would be $500, ,maybe more. We have to have blood work done to see how her kidneys and heart are before the surgery.She thinks it could possibly be cancerous. I am 65 and my husband and I are taking care of our 3 grandchildren because our daughter is in jail because of drugs. W e don't have $500 and I thought mabye there is a healing alternative. I love Kira very much. Is there any help out there? Blessings Mrs. Rowles

Suggest all of you who have similar concerns check out this wonderful natural and effective non invasive therapy:

Sandra M Urquhart from Fort Lauderdale on November 22, 2009:

Your dog doesn't have to die. I know of something natural that can and will heal him. You are wasting your money with the vet. Go to, and read the article on Dying unnecessarily. That is just the first of many articles on this subject and cancer that I will be writing. You can email me directly if you want to know about the product that healed my friend and mentor's dog of cancer. It heals people as well as pets. You also should read the article on that site about Vet care.

Cheryl - Yes I have heard that Prednisone does help. But it is too expensive for me. My vet told me to give Kaos childrens benadryl each day to keep the histamines from building up in his blood. Sounds generic I know but it seems to be working.

Ashley Tyler (author) from Oklahoma on October 03, 2009:

Kaos is doing great. Still very spoiled and playful. He has not had any new growths since he had the one removed. How did your dog do at the vet?

Anita on September 21, 2009:

My dog Daisy looks exactly like your dog. She has a similar bump on her neck.

I have her scheduled to remove "the bump" and hopefully things will come out okay.

How is your dog doing?

Cheryl Victor on June 22, 2009:

I'm so sorry to hear this news about your beloved Kaos. I will pray for him. My sons Pitbull Shankie had a Canine Mast Cell Tumor removed yesterday. I like you have cried and cried over this, we love this dog to pieces, I can't imagine him not being a part of our family. He is only 3 years old. I googled this type of cancer and it says Prednisone can help cure this type of cancer. I am going to call the vet and find out if this is true. Have you gone this route yet? I wish you the best, I will check back to see how Kaos is doing.

Ashley Tyler (author) from Oklahoma on May 02, 2009:

He was 6 years old. I do not think there is any particular age that dogs are more susceptible to cancer...but I do not know for certain.

Janetta on April 29, 2009:

Just wondering how old your dog was when you found the bump. My boxer is a year old and I was wondering if there is a certain age when cancer is more of a possibility in dogs.
