Pet's info: Dog | Doberman Pinscher | Female | spayed | 6 years and 8 months old | 77 lbs
Noticed a firm lump on my dog’s right hind leg. Went and look through her photo and found that the lump was there 1.5 years ago (pls see pic attach). Didn’t really change much, still about the same size. I’m worried about osteosarcoma but it’s been 1.5 years, is osteo still possible? Or could this be a lipoma which she has a few on her body at the moment, but this is firmer than her other lipomas, you can still somehow pick it up but can’t really move much because there’s not much skiN around.

Osteosarcoma is typically a very aggressive cancer so it would be unusual for the pet to be doing well one and a half years later. There are many types of skin masses including benign bone growth. I recommend to play it safe and to have the mass aspirated by your veterinarian. This will give you a better idea of what’s going on and if it’s something that will cause a problem in the future or requires treatment. I hope this helps.
