I am having problems with my EB having skin problems beginning as a little bump then the hair falls out when you rub it. She does not itch and the patches are as big as 50 cent piece. Old spot have had the hair grow back but new ones show up. I have taken her to at least e vet all have ruled out ringworm, mites and the like. They have given medicated shampoo, antibiotics but not has worked. Can anyone help. By the way I have changed her diet.
