This food has worked wonders for my pups! My chihuahua has always had a sensitive stomach, but it started getting worse as he aged. I felt like every 6mons or so, I was spending hundreds of dollars at the emergency vet clinic for "colitis" or "inflamed intestines". He and another one of my dogs started experiencing bloody diarrhea around the same time, due to their previous food. After a couple of days of them eating Hill's Prescription Diet i/d Low Fat Canine Digestive Care Chicken Formula Dry Dog Food
it stopped and the vet told us they could be taken off of it or continue it as their regular dog food. We decided to keep them on and they haven't been to the vet for stomach problems for 2 yrs now. I highly recommend for sensitive doggy bellies! The only CON* is, if you are not buying it from a vet clinic, you have to have a prescription from your vet. Its also a little pricey, but you pay for what you get!
