Science Diet Grain Free I feed my 14 year old Science Diet Grain Free. My dog is a picky eater and likes it. The Vets recommended it after we ran into a dry dog food that was on a recall and my dog got sick. It has no fillers and is healthy and does not put weight on my dog May 5, 2014
This food has great results. We like this food because it makes my dog have to go outside less. He seems quite healthy too. I recommend Science Diet to everyone. August 2, 2014
Great product My dog loves the food. Vet thinks it will extend his life over other dog food out there. I wish it wasn't so expensive, I want to keep buy this food, but not sure my budget will allow. October 22, 2013
My dog loves it! Me and my wife switched from another band that contained additives that could have been harmful to our dog. Hills is gray and our dog loves it! Hands down a great choice June 4, 2015
Food that my dog loved from the start.... I have a dog with various health issues so I'm careful as to what I feed him. I switched to the Hills Grain Free because is was slightly less expensive than the other grain free food brand I was feeding my dog and Hills offers coupons from time to time. From the minute I set the food down my dog loved it and, knock on wood, he hasn't had any bouts of diarrhea (which is one problem I was having with him). Love the Velcro closure on the bag, always a tight seal! October 2, 2014
Our dogs love this food. Our 6 year old Chocolate Labrador Retriever has food allergies, he was on Science Diet WD. Our two 10 yr old Beagles ate it too. Their coats were horribly dry, coarse, brittle, lusterless and they were shedding at an unbelievable rate. We switched to the SD Grain free w/chicken and their coats have improved, they love the taste of the food, their intake is less because of the fat content and they produce a lot less stool. So far except for the weight gain it is working out. The major problem now, is that it is hard to find and it is very expensive. January 7, 2014
My dog loved this I have to feed grain free for my older dog and he is very picky. Had a coupon and tried the science diet grain free and he loved it. October 6, 2014
The Best Grain Free Dog Food! I recently switched all of my dogs to this food (big and small/old and young). Several of my dogs have allergies, stomach, and weight issues. I've tried other grain free foods in the past with no luck - either my dogs didn't like them or upset their tummies. The Grain Free Science Diet is amazing. All of my dogs LOVE the taste and have had no tummy issues at all. I also give them each a little bit the canned grain free version of this food along with the dry. March 28, 2014
