I actually wouldn't recommend this product unless you know for sure your dog's skin irritiation is caused by food. It didn't help my dog and actually made him constipated. He's been on it for atleast two months now and still isn't going to the toilet as well as usual. He can't seem to digest it properly. Plus, the size of the food is too big for him (he's a large chihuahua, 13lbs). I'll admit he's a fussy dog but this really wasn't a hit.
