Rated 4.8 out of 5 by 64 reviewers.
Rated 5 out of 5 by My dogs love it I have two collies from rescue. One is over 10 now and the other is pushing 10 and she still acts like a puppy. I like that Science diet offers a Large Breed formula for older dogs. It is very palatable (I use it for treats, too), and they maintain a nice lean, healthy weight on this food. May 16, 2012
Rated 5 out of 5 by My dogs love it but....... The price of Science Diet has increase so much that it is getting very hard to feed my dogs (3) a quality food like Science Diet. August 18, 2015
Rated 5 out of 5 by 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? May 16, 2012
Rated 5 out of 5 by Love food Hi, my lab is 10 years old, and love the food, but I don´t know why she is still hungry, I just change the food. August 22, 2014
Rated 4 out of 5 by This product is very good for joint issues, even for young dogs. Prices can be too high, unless coupons are offered! This product is very good for joint issues, enjoys. December 3, 2014
Rated 5 out of 5 by 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. May 16, 2012
Rated 5 out of 5 by Feed since a puppy... I have fed Science Diet to my Bull Mastiff since he was a puppy. He is now 7 years old & still seems to enjoy it. The kernels are perfect size for his big mouth. Other brand food is to small & it gets lost in his mouth. Highly recommend Science Diet for ALL breeds. May 16, 2012
Rated 5 out of 5 by We wouldn't give them anything but Science Diet We have had two Chocolate Labs over the past 13 years and have only given them Science Diet Large Breed. Without fail, whenever someone has met one of our dogs, their first comment is "What a beautiful coat!" And they have never gotten tired of the food--still drooling over each meal. Our current dog, CoCo, is eating the Mature Adult brand now, as we like the assurance that she is getting the additional vitamins and supplements that she needs in this stage of life. May 18, 2012
