Rated 5 out of 5 by from It does what it says it will On March 30th, I noticed a distinctive limp and my blue nose mix Smokey not putting any pressure on his left rear leg. The next day at the vet i learned he had Cranial Cruciate Ligament Insufficiency (rupture). In my language he blew out his knee. We had allowed him to get up to 107 pounds. Now we know the dangers of to much weight in dogs. We can not have the corrective operation done until he gets down to 90 pounds. In comes - Perfect Weight by Science Diet. Twenty days later he is down to 99 pounds and well on his way to the goal of 90pounds.At this rate we will have the surgery in three weeks. We could not have done it without Perfect Weight.

Rated 5 out of 5 by from The only food that has helped our dog lose weight! Our beagle mix is obese--about 30lbs overweight. She lost a few pounds on a prescription dogfood (a Science Diet competitor), but then hit a plateau and stopped losing any additional weight. We put her on Pefect Weight and are amazed at the results! She is losing weight--there's a ton of loose skin around her neck and belly. She has so much more energy than she did on the other food. There's a bounce to her gait that wasn't there before. And her coat is so shiny and soft. We are very pleased with this breakthrough new food.

Rated 5 out of 5 by from Worked great! My terrier is back to an Active Lifestyle! After trying many weight-loss products for my 4-year old Yorkshire Terrier without much success, I was eager to give Perfect Weight a try. In the past, he hasn't loved the taste of calorie-cutting diets and usually ends up begging for more food. However, he loves Science Diet Perfect Weight and always seems to be full. He's back to his old self and continues to slim and sustain his ideal weight. I'd recommend this product to anyone looking for an effective solution for weight-loss, without the worry of depriving your little one!

Rated 5 out of 5 by from 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!!!

Rated 5 out of 5 by from Super weight loss diet Our 2 yr old Bernese Mtn Dog had a stroke and was hospitalized for 8 days. He is a very large Bernese and was a bit overweight...actually a LOT wasn't until the stroke that we found out that he needed to loose at least 30lbs for his general health, but also to help with his recovery from the stroke. The vet recommended several weight loss diets and Perfect Weight was one of them. He has been on it now for 4 months and has lost a total of 24lbs...approx. 6lbs/month. He has one more month to go, before he reaches his ideal weight. He has lost the weight rapidly, but not dangerously fast...Perfect Weight has made it much easier than we ever thought it would be. I would HIGHLY recommend this product!!

Rated 5 out of 5 by from Pearles big winter weight loss Our yellow lab gets lazy during the winter even though she is only 3, the vet said she packed on 20 pounds she was up to 65 pounds the same weight as our 5 year old black and tan coonhound Odie. She has been eat HSD once a day, dinner time. She has lost the 20 pounds and looks great. She is a big ball of energy in a mass of muscle. She and Odie both love the HSD. They see the big bag come in the house and their tails a waggin and they beg for a kibble. Thank you HSD for making a food I know my dogs love and keeps them healthy with #1 ingrediants. Pearle and Odies Mom.

Rated 5 out of 5 by from It works for my overweight dog! I have a female black lab/cattle dog mix rescued dog. She has had a little trouble with her weight lately which has attributed to her recent hip problems. (We think she is about 3-4 years old so we think the weight is to blame mostly.) She was 61 lbs and needed to weigh about 55lbs. After about 3 weeks on this product, she lost about 2 lbs. She continues to shed the pounds. I have been feeding her the recommended for the weight she needs to be. I am confident this food will keep her trim and in perfect shape for the long haul!

Rated 5 out of 5 by from 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!
