Rated 4.8 out of 5 by 53 reviewers.
Rated 5 out of 5 by Hannah loves Science Diet When I got Hannah, she was 3.5 years old. Here previous owners fed her a low quality brand. I was reluctant at first to change, but my Vet offers Science Diet if you board your dog. The second time I left Hannah for boarding, I decided to give her Science Diet and never looked back. The first thing I noticed is that her "#2" (why do we dog owners love to talk about #2), was smaller than with the other brand. The only reason I could think of is that more nutrients stay in her body, than get expelled out the other end as waist. Just a few months ago, when Hannah was 7.5, I decided to go for the Mature brand. She loves it even more. I just bought a new bag, and noticed the brand new "velcro" closure. What a great idea! I am sure you will start seeing this type of closure instead of the zip lock type. It works a lot better, and easier if you have arthritis. I just know that I have extended Hannah's lifespan by switching her to Science Diet. Hannah is one Happy Havanese. June 14, 2015
Rated 5 out of 5 by The Small Bites are great. My Trixie is up there in age and missing a few teeth. The small bites are great for her. July 19, 2015
Rated 5 out of 5 by Science Diet! Science Diet, the only food I have EVER fed any of my dogs! December 4, 2014
Rated 5 out of 5 by My little baby loves Science Diet I have a 14-year old Cocker Spaniel and she has been eating Science Diet dry food her entire life. Many people think she is still a young pup because of the energy she still has at her age. I know that because of Science Diet that she has been eating her entire life is why she is so vibrant and active at her age. I will forever use Science Diet for my animals. August 14, 2012
Rated 4 out of 5 by My review My dog really seems to enjoy food time but of course it's a little pricey. September 17, 2015
Rated 5 out of 5 by The best food Will continue to use with all my dogs. This dog food is the best . I would never give my dogs anything else. This food has everything I need for them to be healthy and at the age my pet is he needs only the best September 13, 2015
