I bought this food to switch from the regular Adult Hills Dog food. My French Bulldogs are very gassy and tend to throw up their food. I think this switch has been beneficial as I have noticed they throw up less and seem less gassy!

Perfect diet for my Frenchie

23 days ago

My French bulldog, Lafawndah, is now into her second bag of this food and she loves it! This food works well for her as she tends to have loose stools and occasional vomiting when eating other brands of food. She also eats very fast and we feed her from a special bowl that helps to slow her down. This food has been a game changer for her.

Recipe seems to have changed? Why and how?

3 months ago

My dog had Giardia as a puppy. It disrupted her digestive system for a long time even though she was cleared of it via confirmed labs. This food seemed to help finally firm up her poop. She'd gobble the kibble down until recently when I noticed it changed in size and is larger. She now picks at it a little untill she's starving, then later in the day, she'll finally eat it all. What else besides the kibble size changed in this recipe? Obviously, something has! When companies make changes, they really should explain them on the bag!

Hills Pet Nutrition Consumer Affairs

Thank you for your review. To maintain our leadership in nutritional health care for companion animals, Hill’s periodically makes changes to product formulas to incorporate additional health or product design benefits. Hill's Science Diet Adult Perfect Digestion Salmon, Whole Oats, and Brown Rice Recipe Dog Food had a formula upgrade in 2025. We generally suggest doing a 7-day transition, as this allows the pet time to get used to the new flavor and ingredients. We are disappointed to hear that we didn't get your dogs taste of approval for the formula upgrade and we will be sure to share your comments with our team. Additionally, we offer a 100% guarantee on our products; please contact the retailer if you would like to return this purchase.
