Skorch lost a toenail last spring. Actually, it was hanging. I took him to the vet who just pulled it off. I tried to keep it clean. The vet didn't give me any kind of salve to put on it, but I'm a good one for Triple Antibiotic and used that.
The nail has grown back but it is growing almost straight up. It's weird.
My poor boy Skorch is missing several nails. He has one that is skinny with ridges. I don't know if it is from racing or for another reason. They were missing when I got him.
The groomer from Petsmart only charges me for the girls when they go in for a nail trim. She said Skorch doesn't have enough to charge for. (Not really true, but I'll take it.)
