Rated 5 out of 5 by from Great Product-it delivers! I highly recommend this product. I first started feeding this to my rescue (4 years ago). She was over 10 lbs overweight when I got her. she lived in a foster home for nearly two years and was fed table food often. Within a few weeks of feeding her this formula she was down to her ideal weight. I continue to feed her this, but being that she is now approx 8 years old I may have to switch to a Senior formula. I have a many dogs over the last 25 years and have always fed them Science Diet and am very pleased with all formulas. Years ago I switched to a cheaper brand and immediately went back to Science Diet. Thank you for a great product to keep our fur babies healthy and happy!

Rated 5 out of 5 by from Hill's Science Diet Adult Light is a wonderful product! We have 3 female indoor cats & our vet recommended Hills Science dry food for them. He gave us a small bag to have them try & a coupon to purchase a bag if they liked it. They all liked it right away & I switched to the Light because they dont go out so they arent as active. The 3 of them are the correct weight for their size & ages & they have beautiful coats of fur! Our black cat Midnight has an extremely shiny coat. I have had cats all my life & always gave them the inexpensive grocery store brands until now. I will never switch my cats back...we are sticking with Hills Science Diet!! :)

Rated 5 out of 5 by from Great Food My Australian Shepherd has been overweight since he got neutered. We switched him from advanced fitness to the light formula after talking to a hill's representative. He will eat just about anything, but he really likes this food. My other Aussie even tries to sneak and get some of it! I think it is worth the money over grocery brands. The biggest bag usually lasts him longer than a month. I have seen conversion of fat to muscle, and he seems to be enjoying himself more. Would definitely recommend this food to other overweight or prone-to dogs.

Rated 5 out of 5 by from ADULT LITE SCIENCE DIET I have had my nine year old rat terrier on it for many years. He does give me the look of "not this again" but I just shrug my shoulders at him. This particular food also seems to make him do a lot of #2's in the yard. I don't know if it is the foods way of keeping him "Lite" or his way of paying me back for feeding it to him. On an occassion when around another dog's food he will eat theirs like he's stealing it (usually a cheap brand). He never does that with his food. He does burp after some of his meals so I'm guessing somedays he likes it and when around another dog's food, he doesn't like it.

Rated 5 out of 5 by from This product helps keep the cholesterol down I had a schnoodle that the cholesterol would settle in her eyes and this made it difficult for her to see. This product was recommended by the eye vet. Now I have two schnauzers and I have them on it to help prenvent the problem I had with my other dog. I was told this is a problem with the schnauzer breed with the eyes. I highly recommend the use of this product so you will possibly not have to hurt because you pet might be going blind because of not being able to process the cholesterol.

Rated 5 out of 5 by from Great for maintaining weight My senior dachshund is currently eating this food as has enjoyed it for over a year now. He became very overweight and was put on Hill's r/d in order to lose the excess weight safely, and once he reached his goal weight he has been eating this to maintain and has done very well. His coat looks great, he has a great amount of energy for his age, and he LOVES eating it. I really enjoy feeding my dogs a food that has the research behind it by using Hills/ScienceDiet/Ideal Balance products.

Rated 5 out of 5 by from I am happy and my pets are healthy It seems like my yellow lab looks at food and gains a pound. I put him on science Diet Adult light and without having to change the amount I was giving his vet said he was down to his ideal weight after about three months. He's continued on that food and has maintained his ideal weight beautifully. I also have a cat who is on Hill's prescription diet for joint health and I'm so happy that he loves it considering he refuses to take any other kinds of joint support meds and he has gone through hip surgery. Overall, I'm very pleased with Hill's products.

Rated 5 out of 5 by from Excellent quality with good results My two Cairn Terriers had put on a little excess weight. Our vet had suggested that they switch from Science Diet Adult to Science Diet Lite dog food. He has always recommended Science Diet. We had a coupon for a free small bag of the Science Diet Adult Lite. Both dogs took off the extra weight over several weeks, liked the food, and didn't seem to notice that they were getting less calories. Seems like a win win situation. The cost is a little high, so I'm alway looking for sales or coupons. I do think Science Diet is good quality though.
