It all depends what type of intolerance the dog has to be honest but with raw you know what you're feeding and can remove anything from the diet that causes problems.

Chances are though it'll be something that is only found in commercial dog foods or that arises from the processing of foods so a raw diet of any kind would more than likely sort the problem out fairly quickly. Presuming the vets diagnosis of a food intolerance is the problem.

Like Andrea said it won't do any harm.

If you do decide to feed raw make sure you do lots, and I really do mean lots, of research before you start. If you decide on that route drop me a message and I will direct you to some good websites and answer any questions you might have!
