Rated 5 out of 5 by Great product My dog has been eating science diet from her puppy years through all the stages they offer and now as a healthy 15 year old she still eats active longevity. Most large dogs don't last this long and I'm eternally grateful for all the years I've had with her and thanks to science diet food for helping keep her so healthy and energetic through all the years.

Rated 5 out of 5 by Certain words which require spelling, at times Dante is a survivor. He's required two known shelter adoptions (near death experiences# and another unofficial adoption to wind up sleeping at the bottom of our bed. Dante is at least 12 years old and probably older, with whatever is the current dog year factor to consider today. Dante has four favorite words which require almost immediate reaction from his companions #my Wife and myself#. They are: 1) eat, 2) walk, 3) ride, and 4) treat. Dante is adorable but he's a bit of beggar. He has many skills including the ability to beat me on numerous occasions, playing "Let's Stare and the first one to get distracted or Blink loses". Well, he totally enjoys his Science Diet Dry Dog Food for mature dogs in small bites. If any of the above words come up in conversation prior to the scheduled times, be prepare for a stare down, spin move, or bark #saying well let's go#. We are attempting to help him recover from a pulled legiment in his right rear thigh and to get him healthier as a result of his recover. The only treats he will consider, have medication that help. And to boot, he is more stubborn than an old mule in the Summer heat. Dante is a connoisseur with refined taste buds and we are happy to serve him only the Best - Science Diet Products; he would not settle for less... May 16, 2012
Rated 5 out of 5 by Always been pleased with Science Diet! I have now had several dogs raised on Science Diet foods. My current "children" are a 7+ & a 14+yr old Pug. They are my "recycled Pugs", as I adopt breeding dogs that are retiring. I am on my 3rd older Pug on Science Diet and they have all done supremely well- my old girl looks several years her junior, from others I have seen. She takes a little Rimadyl for her spinal arthritis, but has no other health problems. I have had her since 2004 and I attribute her overall condition and health to Science Diet! Recommend Science Diet foods to everyone, all of the time, especially after they comment on how great she looks! May 16, 2012
Rated 5 out of 5 by Hills Science Diet Small Bites Mature 7+ I was buying this for 1 of my elderly dogs due to it being so easy for her to eat and digest. Her teeth were wore down in the back and she had cancer too. This food was perfect for her and she loved it. We have since had to have her put down due to her cancer, she was 12 & 1/2 years old but had an AWESOME life and was VERY LOVED. This food i believe helped us keep her for a few more years, she also had arthritis and this food helped her to stay active. RIP my Sugar. June 24, 2014
Rated 5 out of 5 by Complete Nutrition for my Dog I have been using Science Diet for over 10 years for my Daschund. He has been picky about food since the day I got him and Science Diet is the only thing he will eat, and I have tried many different dog foods. He is picky to the point that he will only eat the small bites. It doesn't matter much to me, because Science Diet has a great line of products for my dog and as long as he likes them, I am happy! Thanks Science Diet! August 21, 2012
Rated 5 out of 5 by Perfect for pugs I have a 9 year old pug that has been transformed by Hill Mature Adult small breed formula. He was scratching and had constant ear infections on his previous diet. After eating Hills for 3 months his coat is smooth and soft and his scratching and ear infections are gone! He also eats the canned mature adult beef formula and loves it. Thank you for making such a healthy quality product my pug enjoys. Julie M. and Bacio the pug January 13, 2013
