Q. What can I put on spots , when my Lab loses his hair?
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. Hair loss can have several causes, including parasites like fleas or mites, allergies, and hormonal diseases like hypothyroidism. Unfortunately you have to know what's causing the hair loss before you can figure out how to treat it. Schedule an exam with your vet in order to determine what's causing the hair loss and get appropriate treatment. And I don't recommend using human topical products, as they may not be safe for dogs to ingest, which they will often due when they lick.
