The first year of our puppies life was trying to figure out what she could, and could not eat as she had a sensitive stomach. These were the only cookies she could tolerate for the first few years.  I highly recommend them if your dog has a sensitive stomach. Unfortunately, our vet told us they were no longer be able to get these, so we had to find an alternative. 

The Purina pro Hydrolized plan of dog food/treats is the only brand I use for my 2 pups. It's pricey but worth it. My pups are super sensitive to everything and this brand is the only brand they can watch without getting upset tummies. I also use the Hydrolized dry dog good and the Hydrolized canned dog food.

I got this snack for my very allergic mini pinscher and he really liked it! It is hard to find something that will keep him from allergic reactions but this do him good.
