My 6 month old calf has about a 1/2 inch part of her hoof peeling off down by the bottom of it. It is about 2 thin layers peeling off. I haven't wanted to fuss with it, but I don't want negligence to make it worse. She sees the vet for round two of vaccines in about 3 weeks. Should I call him sooner or leave well enough alone? It isn't causing any lameness or other problems.
