My long-haired collie has developed skin disorder-dried spots of skin that leave open surfaces-he doesn`t itch

He`s 3 yrs. Treated this with anti-biotics and medicated shampoo, which greatly helped, yet I still notice occasional quarter-size area of raised dry skin-it can be rubbed off which leaves an open sore. He doesn`t itch, yet I`m concerned that he is susceptable to other disease from these open areas. Anyone with a collie ever heard of such a skin disorder?

I agree that it could be a food allergy, and allergy to corn is certainly possible. Most good dog foods have so many ingredients nowadays (corn, eggs, cottage cheese, carrots, chicken, etc etc) it may not be possible to figure out what he is allergic to.





Look into Natural Balance dog foods, carried at Petco and other places. Each dog food is formulated with only a single carbohydrate source and a single protein source that is not found in most other dog foods, so it is unlikely that your dog has ever been exposed to it before and would not likely be allergic. My dog has done well on the Duck and Potato formula for a year and a half after he got allergic to Innova.
Reply:You need a dog food that "does not" contain any form of corn. We used a dog food with a rice base.
