For years my mothers dog used Hills I/d digestive care with turkey canned food but in 2015 of late September we bought 3 more cases from local vet shop like always. This time the dog started to throw up at times then after into 2nd case dog got real bad. We tracked it to the dog food only, dog lost 5 lbs. We took rest of bad food back to vets store, told doctor. We have now switched to Beneful with no problems anymore. I guess we got some bad cases of Hills I/d. Thanks.
