My female Jack Russel is 8. She has these spots at all four areas where her legs meet her body and a few on her belly/chest. They are black but not thick skin. There is no hair loss in the leg areas but a little on the belly/chest. She does seem to scratch quite a bit. Is this the same as you were saying above even though her skin is not thick at all...? Is there anything I can do to help her before going to the vet and how long would it take, approx, to see a change..? Thanks for your help.View Thread
