Lump on my dog.

Species: Dog
Breed: Border-Collie Shephe
Age: 2-5 years
Hello Dr. Marie,

I sincerely hope that this is real, and that if it is and you scanning through questions that you've hopefully stopped at mine.

My boyfriend & I adopted Shreddy roughly two years ago from a family with one too many dogs and too little space. He had all of his shots and his papers of proof. After a while had passed I noticed he had a lump on his chest a bit smaller than a golf ball. Dog breeder friends of ours told us it was probably just a fat deposit and not to worry about it. Shreddy has now come up with yet another lump on the left side just next to his manliness. Please respond with any possibilities of what it could be- my brain keeps thinking cancer


Online vet, Dr. Marie

Dr. Marie replied:

It's really hard to talk about lumps without being able to feel them and see them.

It is really common for dogs who develop fat deposits (lipomas) to develop more. The only way to know for sure though is to have your vet do a fine needle aspirate test on it.

Most cancerous lumps tend to be very hard in texture, irregular in shape and often will look "angry" - i.e. red/purple.

It's probably best to have your vet take a look just to put your mind at ease.

Dr. Marie.
