Some American Bulldogs suffer from entropian. Entropian is an extremely uncomfortable condition for a dog, the eyelid or eyelids curl inward causing the eyelashes to rub or scratch the eyeball. Obviously we do not breed dogs that have entropian, sadly, there are breeders that do. Surgery can be performed on the eyelids so that the eyelashes grow outward, giving the huge relief to the dog. Please do not buy a puppy from a breeder that breeds parents with entropian.
