Rated 4.8 out of 5 by 84 reviewers.
Rated 5 out of 5 by Product delivers the benefits listed. My Shih-tzu was at 13.5 lbs. when I decided to put her on Scence Diet Pefect Weight and within fourteen weeks she was at her ideal weight of 11 lbs. She did not even know she was on a diet. Great Product! November 22, 2014
Rated 5 out of 5 by Great product for low energy dogs.... I have a low energy Pitbull that burns little calories and loves to eat...I've struggled to get her to the perfect balance for years. Some foods had to high protein others not enough etc. My vet recommended the R/D as a short term solution to loosing a much needed 10 lbs. The R/D worked but was the only food that kept her weight down to near normal. After 4 years of the R/D I was in the process of moving and was unable to get my regular order. I ended up at the local Pet Smart where I was planning on getting the low cal Hills and found the Hills Science Diet Perfect Weight. It was brand new at the time but I tried it. Its been about 8 months and this is definitely the answer and more affordable. My dog has lost 5 pounds in 6 months from changing from the Hills Science Diet Prescription Weight Loss R/D. 2 cups a day and seems to be satisfied with the portions. After all these years, trying at least 10 different types of kibble this one is the winner! Thank you Hills! September 24, 2014
Rated 4 out of 5 by I like the Perfect Weight style food of Science Diet and have been using it for some time! I have a Service Dog, so my choice of food for him is very important! I started Triton on this food when my Vet informed me that my previous brand actually had too much protein content for a large dog! I didn't even know this was possible! After a lot of research and consideration I finally decided this was the best food for my donated (yet very expensive) service dog! The transition was easy on him. We have been using Science Diet for approx. two years now! However, I would love to see more coupon opportunities! September 23, 2015
Rated 5 out of 5 by Keeps my Tripawd trim! I have a three legged Australian Shepherd. He tends to gain weight easily since he can't be as active as he'd like. I switched him to this food and it has worked wonders! He can still eat the same amount of food, but with a lot less calories. It helps keep him nice and trim and able to enjoy life! July 28, 2015

Rated 5 out of 5 by Mandy loves Hill's Science Adult Perfect Weight food Mandy is a very picky eater for a 9 year old Beagle, but once she tried the Perfect weight food, she really loved it. It gave her more energy to play and run, her coat is nice and shiny and she has not begged for more food. She has lost 5 pounds and going on strong. I am happy that we decided to give her this food because I have tried all different dog food to help her loose weight and nothing has worked. Keep up the good work Hill's Science!!! Your friend Mandy Davis July 25, 2014
Rated 5 out of 5 by Healthy dog...healthy droppings for clean up Our dog loves this food! She never has a problem with it and she maintains a healthy weight. Best part, the clean up in the backyard is easy. Whatever she eats, comes out well formed and easy to clean up - never too soft even after a heavy rain. This is part of my motivation to pay a higher price for food! November 22, 2015
