my dog has got two little bald spots with dry skin took her the vet she was checked and had no ringworm, mites or fleas. reason for going the vet was because i had no idea why plus i have a 1 year old daughter and didn't want her to catch anything if the dog did have them problems. has anybody else whos got a pat ever experienced this unexplained for loss of fur does it grow back? the vet says its common in these dogs no treatment was needed. people have said mix cod liver oil with her food is this wise will it help or is it a stupid idea.
