Large lump on back.

Species: Dog
Breed: mutt
Age: 11-15 years
hi. my dog has a large hump on the top of his back. it doesn't seem to hurt him at all but i was curious what you think it could be.it looks like it keeps getting bigger.right now it's the size of a softball. should i be concerned about it being something that will eventually get so bad i will have to put him down. thank you in advance for your response.


Online vet, Dr. Marie

Dr. Marie replied:

There are lots of things that this can be.

It may be a lipoma which is a fat lump and nothing to worry about.

It could be an abscess. If this is the case it will need some surgery and antibiotics.

Any time there is a lump I recommend having a vet take a look.

The vet should be able to tell you whether there is a concern for cancer or not.

Dr. Marie.
