Porkchop's paws look like they are miniature overgrown toenails. His back issues are such that he can't go for walks anymore so there is no rough surface to 'exfoliate' the paw pads. His left leg sort of twists when he walks also, which the vet attributes to neuro damage due to the bone spurs. In the attached photo, those yellowed things on his left rear paw are rather tough and minimally flexible. There are black ones on the pad to the left of the white pad. Here's my question-I've been putting cocoa butter lotion on them which softens them but they aren't coming off. They are getting thick and I think offsetting his foot placement more than the back issue. I've toyed with maybe holding him down and using nail clippers on them. He doesn't have these on his front feet but he paws at the carpet several times a day with the front feet. There is no sign of a yeast infection and his nails are trimmed. I thought maybe he's able to keep the front paws in shape by pawing. (He's tearing up the carpet though.) Any suggestions? Have any of you seen something like this?
