Today I noticed that Drake's rear hind leg is swollen and he seems to be favoring the other one. I took some pics, see below. Also, since I do research in X-ray imaging at work, I took a couple of X-rays which I'll share here. I sent these to my vet, but I'd also like to hear any professional opinions out there. I'm putting them both regular and "inverted" since these were taken digitally I'm used to seeing them inverted compared to what vets would normally see.
