We love this product and so does our dog! She "talks" to ask for her Science Diet Dog Food! Our dog Chloe is a 7 year old yellow lab and has been on Science Diet for Large Breeds dog food since we first got her as a new puppy! She can't wait for her bowl of Science Diet, and even "talks" to ask for it! Crumbs are flying as she devours her Science Diet, she has always loved the taste! Her vet recommended it, and this is all that she has been fed for her entire life. Her coat is so beautiful and shiny, and she has always been so healthy... never needing to go to the vet other than wellness and vacination visits! Her check ups are always first rate and she continues to maintain her ideal weight. She is so playful and happy, runs, goes for walks, chases birds, and loves her family with great "puppy-like" exurberance, even at almost 8 years old! The proof of quality of the Science Diet brand is in the health, vitality, and beauty of our beloved Chloe. We have always highly recommended Science Diet brand dog food to all of our friends with new puppies and older dogs alike. May 30, 2012
Less waste and great nutrition Great product. Pets produce less waste and enjoy the food. May 20, 2015
5 happy dobermans My wife and I have 5 adult AKC registered Doberman Pinschers. Black and Tan Male and Blue female parents to three pups kept from their breeding. Two Black and Tans and one Red.From birth to now all have been primarily on Hills Science Diet to the tune of approximately 200 lbs each month. Their overall health, coat condition, and digestive function are a direct result of their diet. For the money and benefit we wouldn't use any other brand and haven't for over 7 years now. We have seen from time to time the pups ( now almost three years old) and their respective owners and it is very easy to tell who is feeding Hill's Science Diet and who is not. When they see our Dobes they always seem surprised at how much healthier and larger they are and our first question is always "what are you feeding them?" Invariably the answer to the sub par looking pups is always a brand other than Hill's. Proof enough for us! May 16, 2012
Thanks! Have 2 healthy dogs (babies) that have grown up with your products, specifically this dog food! Thanks for providing a good quality food that my pups love. Plus, I get never ending compliments on their soft and shiny coats (even though they both have short hair!) Thanks for the extra fish oil. October 14, 2014
This dog food has many great qualities! I have had three Great Danes now, and all of them have eaten the adult large breed or the lamb and rice adult large breed food. We switch between the two just for a variety in taste and my dogs love both! Heck the one eats 9 cups a day and is still growing; while the other eats 6 cups a day! I really value that our pet store gives a free bag after every ten, we go through the dog food, but I would never comprise my dogs health to save a buck! They are part of our family! Thanks Science Diet for always taking care of my family! May 16, 2012
My two dogs love this food I have two large breed dogs and they just love this food and can't get enough of it. I have a Saint Bernard and a mixed breed which is Bernese mountain,black lab & rottweiler mix May 18, 2012
Great food I keep my 140lb Anatolian Shepherd on this food. He loves the taste and I definitely don't mind the price! July 28, 2015
This is a must have pet food. Before I picked up my German Shepherd from the Humane Society, she had lived with cruel previous owners. We took her to the same veterinarian that her previous owners took her to, and he said they nearly broke her leg. He says they did this because they fed her second rate dog food, and she had an accident in the house. She couldn't help it at all, but they still hurt her. When we first got her, she was extremely hand shy, and seemed really happy every time we fed her throughout the day. She loves her dry dog food, and loves it even more when I mix treats sparingly in it. Though the price for the large bag of dog food is a bit high, I feel good knowing Hill's Pet donates to Humane Societies regularly. This is a good dog food at a good value, and now that we have a kitten as well, he is on the Science Diet also. I highly recommend this brand to anyone with a furry friend. August 7, 2014
