    By on

    I used Science Diet "Perfect Weight" as recommended by my vet to help my chubby dogs get down to a good weight. One dog is a 4 year old female pyrenees with a hip problem. The other dog is a 7 year old Ovcharka and we don't want him to develop arthritis. Once they got to the weight she wanted them, she recommended the "Adult Light" to help maintain that weight. It seems to be working well for them.

  • Just What Zoey Needs

    By on

    We buy Science Diet Light for our special needs dog, Zoey. She is diabetic and was on a food that was harmful for her health. With this, she has lost weight, as suggested by our vet, and her glucose levels are much more stable. It's such a great food for Zoey, my senior Aussie, Teddy, gets it too.

    When my lab was a puppy she didn't handle other brands well, suffering with intestinal discomfort. My vet recommended switching to Sience Diet and she has no discomfort! Now she is 4 and has thyroid issues so we switched to the light version. No stomach issues still!

    My doodle seems to enjoy this as much as her usual Science Diet food. Only problem I have with this product is it does not come in a smaller size than 33 lbs.

  • Great product

    By on

    We switched our dog over to Science Diet a couple of years ago and he loves it. This food seems to keep him in great shape and (apologies if this is tmi) his poops are consistently solid and easy to bag up. Our dog is large (~65 pounds) and he has a lot easier time eating the large bites than the small ones. We highly recommend this product!
