Rated 5 out of 5 by from A food I feel good about feeding to my dog My 11 1/2 year old Belgian Malinois is a huge fan of Science Diet Mature Adult Large Breed. I briefly changed him to another food, which I thought was going to be a better value...but he quickly put on weight--alot of weight. And extra weight, especially in an older, large breed dog, can spell disaster. With this food we were able to get him back to a healthy weight in no time, and now he has more energy. Other than his white fur, you would never know how old he is--because he is still able to run and play! It may cost a little more than that other brand, but it is worth every penny in keeping my dog healthy.

Rated 5 out of 5 by from What comes out is as important as what goes in... I have taken to rescue dogs... and they have taken to me. I have 4. The fact is, taking care of a dog - any dog/dogs - is more than feeding and sheltering and exercising them. It's also the cleanup of what they leave behind... and what goes INTO them can effect how their coats shed, and their other, uh, needs... nutrition, of course, but also the plumbing. <grin> This food has my guys running smoothly, predictably, and comfortably. It allows us to really love and spend quality time together all day, every day. And I tried NUMEROUS other foods before we could say that!

Rated 5 out of 5 by from Endorsed by my 12 yr old puppy! We have multiple dogs, all rescues. One of them came to us in early 2003. He was a 100lb 3 year old shelter dog, frightened and ravenous. The first few weeks he managed to barrel his way past us out the front door and ran, but luckily we got him back unharmed. These days, 9 years later, we open the door and he stays put. We think it's because he knows where the food lives. He's now 12+ years old and a svelte 74lbs. He runs around the yard with the other dogs like a puppy, and he can jump high enough to see over the 7' block fence. He's healthy, has a shiny coat, and he's a very happy boy. I attribute that to quality food and lots of love. What more could you ask for?

Rated 5 out of 5 by from any science diet food all my dogs eat Science diet, My dalmatian lived to be 16 in great health and playful even into old age. I've worked for veterinarians for 25 years, I've seen many clients get new puppies and see then developed and live to old age. The ones that lived the healthiest and longer better quality of lives were always feed the best foods. Science diet is one of those foods. grocery store or ware house foods are like feeding junk food to you pet every single day. stick with Science Diet its a great product!!!

Rated 5 out of 5 by from Wouldn't Change Products For Anything I'm going on 60 and I've fed all of my dogs Science Diet, the original (not the newer naturals). Each of my dogs, and there have been many, thrive on this food. Regardless of the media, I'm a firm believer that, even though my dogs are as important to me as my family, their nutritional needs differ from humans and from all past history, Science Diet has proven to provide a very healthy and long life and I believe provides exactly what my dogs need in every nutritional aspect. They can keep these new fangled products. I'll stick with what I know works.

Rated 5 out of 5 by from Great value! I started my dog on Science diet about 3 years ago and noticed a change after a few months. Not only did she shed those few extra pounds, but her coat has a beautiful sheen that she didn't have while feeding the other mid-priced dog food. In the end I am only paying a few dollars a month more vs. the mid-priced brands, as Science diet has less fillers and other stuff she doesn't need, so she gets full on less. Also there is less waste to scoop, as she ingests less unneeded fillers! Worth the couple dollars extra!

Rated 5 out of 5 by from Great food that my dog LOVES! My 8 yr old Deutsch Drahthaar eats this food and looks and feels great! We have tried other formulas and other brands and he just doesn't do as well as he does on this food. He has lots of energy, his coat is shiny and thick, and most importantly he LOVES it! Thanks Hill's for making great food that I know I can count on. I want to give my pet the best and that is exactly what you offer.

Rated 5 out of 5 by from My Dogs Love Science Diet! Me and my husband rescue dogs and we have 4 dogs right now and they love eating science diet. We have never fed them anything else besides science diet. Sometimes i wish science diet would come out with more coupons for all their types of dog food. It would always help out with who has to buy dog food every week. Our dogs run out of the big 30 pound dog food almost every 9-10 days so we have to keep buying more dog food.. We love feeding them science diet and will always feed them science diet =)
