Thats what I was thinking.
All dogs are different, one food may be great for one dog and another may have a problem with it. Even if it is a decent brand.

Did the vet say or did you ask what he's allergic to?

Also did you only take him to the vet once? Some parasites may not show up on every fecal, you may need to have another one done. Besides if it's happening this many times I'd really suggest you bring him back for a second opinion.
