    Older Dog Gobbles It Up

    By Wren on Jan 10, 2021

    My 11.5 yr old pit bull has been eating this food for 2.5-3 years. Her discomfort from arthritis improved when this food was introduced. She previously ate Crave and had digestive issues and seemed to have more joint problems, she immediately responded positively to this food. After nearly 3 years the food quality has not changed in any noticeable way, the formula hasn't changed, and no one can believe that she is 11.5. She looks and acts like an active young adult dog. Highly recommend this food.

    Autority Chicken & Rice dog food

    By Maggie on Jan 21, 2021

    In all fairness, I cannot give a true report. My dog does not like the food. For years I gave her good dog food but with her health and age, I wanted to give her food for better health. I have tried several brands and got the same result as with Authority. Sorry.

    eating it right up

    By lanieinct2 on Jan 17, 2021

    My golden took right to this food. I find the kibble small for a large breed but he doesn’t seem to mind. Transition was was easy. Purchased before and it’s on our rotation to keep him interested in his meals.

    Great senior food

    By Zoegirl on Nov 12, 2019

    Love the small kibble, which made it easier to chew for a senior dog that is missing teeth and easy to digest my also feel the extra ingredients to help with her bones is a plus I have always said her Grain free kibble and that was a bonus for choosing this food I love that it's made on the East Coast where our live
