We recently had Oz fixed and everything seems to be healing up normally, its been about two weeks and hes almost completely healed, but.... When I check his scabs and where his testicles used to be, I can feel two little lumps, almost like two little testicles where his, well, balls were. Is this normal? The vet checked it at ten days and said everything was fine, but still... Im not sure what those are, and the previous dogs that we had that were neutered didnt have those, atleast that I can remember... Also, he seems to just fall down the stairs and up the stairs sometimes. Like he forgets where his back feet are.. I normally wouldnt worry, but hes done it a few times now, and you think he would learn, however, he keeps hitting his back feet one the edge of the stairs walking up and stumbling. This only seems to happen on the three stairs leading off the deck into the yard. Is he just being a goof, or should I take him back to the vet?
