It’s been just over 14 months since I started an auto-ship , for Purina One True Instinct Lean Muscle Support High Protein Real Beef Dry Dog Food from Chewy with the intention of having my 4.5 year old , 105 lb +, Irish Wolf Hound, American Pitbull mix, lose some weight , while eating the same recommended amounts of previous purchased Purina products and lose weight. While 9 lbs. isn’t staggering, he’s leaner and heavily muscled. His chest appears bigger, waist smaller , and hind quarters you can bounce a quarter off of . He’s much more active and confident. The best thing is, except for changing the product, We Did Nothing Different. Same recommended amount based on weight, To The Low Side Of The Range. He never even noticed the slightly decreased amount over time. We have tried most of the appropriate Purina Ones products here on Chewy, over the past several years, and have never had an issue with product or service. We’re switching now to Purina One + Natural Large Breed Chicken Muscle & Joint Support Dry Dog Food , with confidence knowing he’ll continue to keep his ideal weight & some dietary improvement to support joint health & immune support .

True Instinct, Lean Muscle Support, High Protein

My Dog seamed to really enjoy it when I first bout it. But I wanted a larger bag, and couldn't find a larger bag in stores.

High Protein but Low Fat and Calories!

Perfect for my dog who competes in sports and needs the protein without all the excess fat and calories since he holds weight easily

Product arrived in good condition, but dog is hesitant to eat. Must say all packages were marked best used by July 2025 and contents seemed old and "rubbery" (at least for the product supposed to be poultry. May be a little old. I do have a picky eater and even adding some of Lucy's doesn't make it more palatable for him.

Bear eats this dry food as she does all the others but would ideally would love some raw meat.
