I noticed a lump on Kite around 2 1/2 weeks ago. On the outer side of her thigh, at first it felt like a small hard knot in the muscle. Over the next few days it became larger and puffy and I could see the outline in her fur, which I hadn't noticed at first. So I got her to the vet on Thursday and they took cell samples which came back as indicating inflammation. Vet didn't know what it was, but said it didn't feel or look like the lipomas that commonly occur in older dogs - Kite is 9. Since Sunday, the lump has reduced back in size and now feels more like it did when I first felt it - still distinctly there. As her fur was shaved, I can't tell if the outline looks any different. If it had been the result of an injury, I'd have expected her to be more protective of it when I was feeling it, but she hasn't responded at all; didn't flinch when the samples were taken, even. I'm just curious - any ideas what it could be? Of course I'll be keeping a sharp eye on it, and if it gets bigger or changes again, she'll be more fully investigated.
