Rated 5 out of 5 by from Premium Food Great food for all four of our fur babies. Three mini doxies and one chihuahua mix. They all love the taste and since being on this food, have had absolutely no stomach issues (been on it for approx one year). Plan to only buy this product as their food.

Rated 4 out of 5 by from Mikey loves his "cookies" I have to practically hide the food. You'd think he hadn't been fed in two days. He is definitely a spoiled brat! I don't care, as long as he's happy that's all I need.

Rated 5 out of 5 by from If your dog had pancreatitis, this is a good low fat dog food. My dog is healthy and loves it I have a seven pound miniature dachshund who gets this food because it is low fat. She had pancreatitis and was extremely ill. Following her illness, but a short while later, the vet said we could resume her regular food slowly but she became ill again. At that point we were told a low fat diet was going to be needed for the rest of her life. Hills website made it easy to check the fat content of each of their dog food product. The Adult Light Diet is about the lowest fat content that I could find. I am very thankful for the website information. It was very clear and in more detail than other sites I reviewed. My little Dachsie did very well on this food. It is one year since she had the problem with pancreatitis and no recurrence of her illness on this food. She is now healthy and energetic and has a beautiful coat. She likes the food too. As a treat, and to maintain the low fat theme, she gets a heaping teaspoon scoop of canned pumpkin with her morning meal (no pumpkin with evening meal). Cheerios are her treats. This detailed information is provided as this problem of pancreatitis is not so uncommon and it worked for us. The small bites size of the pieces is about 1/4 inch spherical. The regular sized pieces is about 1/2 inch diameter and 3/8 inch height (cylinder shaped). I like the regular sized pieces for my dog as she chews each one. The small bites are too small and she gobbles them down too fast. She actually started choking on the smaller stuff as she was pigging out and eating too fast. Since I have other dachshunds, this encourages competitive speed eating. However, I made a mistake and ordered the small bites for her. Till this bag is finished, she will get large rocks in her bowl and will have to navigate around them to eat her food. It will slows her piggish consumption while eating. Chewy offered great service and fast shipping.

Rated 5 out of 5 by from good product for weight loss My little maltese had gained half a pound which is a lot for a 6 pound dog. Cutting down on his regular diet didn't help so we switched to the lite small bites by Science Diet. My dog loves it and is very slowly-as planned- shedding that extra half pound.

Rated 5 out of 5 by from Great product Hill's Science Diet is given to the military dogs, and that's good enough for my dog. Besides, it's the only dry dog food that she's been eating for years. It's also recommended by our vet.

Rated 5 out of 5 by from "The Girls" Sophie and Sadie seem to really love it! Our dogs were getting a little heavy from the long winter so our vet recommended Hill's Science Diet Light and our girls seem really happy with it! They love getting the package of dog food in the mail every two weeks! They freak out and run circles around the box! Love your service!

Rated 5 out of 5 by from Great service Our vet recommended Science Diet in the late 1980's when we got our first Sheltie. I've had 4 shelties that lived to be 12 1/2 and older and I believe it was the Science Diet that kept them healthy. My little Scooter and Paisley love the food and can't wait until eating time.
