We have a six month old staffordshire bull terrier who has three or four small areas where he has lost the hair. We have taken him to the vet who perscribed fuciderm which hasn't seemed to make much difference. We know the areas aren't being scratched off as one of the areas is on the middle of his head. He is also starting to lose the hair from around his eyes. We have been told that staffy's can be prone to skin complaints. Can it be diet related? are there any supplements we can give him? any ideas ?
