The question about the lipoma reminded me- my parent's dog has had a hard round lump under the skin of her outer thigh for a couple years now, and we have no idea what it is. the vet keeps an eye on it and the general consensus is just that its pretty weird but it doesnt seem to be doing any harm. out of curiosity do you have any idea what it could be? it's much firmer than a lipoma, it's usually 1-1½ inch diameter but it grows and shrinks a little bit over long periods. The dog is around 5.
There is absolutely no way to tell without a biopsy of some sort but at least it’s unlikely to be something dangerously malignant right now since it’s been there so long without causing problems?
