    Great food!

    By Authority on Nov 15, 2020

    We tried this, because our dog wasn’t eating. The first order we received, she gobbled it up! We then got the wet food as well, and I can tell you, she doesn’t want anything else! She loves this food, is eating well, and appropriately. Thank you Authority!

    Helped with Allergies!

    By Sadie on Jan 3, 2020

    My dog has terrible allergies, especially to chicken. She's been on a prescription diet ($97 for a 26 lb bag) for 2 years now. The cost of her food wasn't a doable option for me anymore, so we switched to this after someone recommended it. We're 2 bags in and so far, so good! The food does have a strong smell; however, it doesn't seem to deter my dog. She eagerly waits for breakfast and dinner time now when before I could barely get her to eat.

    Great food

    By Trod on Dec 7, 2019

    My dog has a horrible allergy to chicken. She will break out in hives. After trying several other brands this was the first one that she wouldn’t have a reaction to. We have stuck with it and haven’t had any issues.

    I have a Great Dane who has been on a $95 (25lb) bag of food for two years due to chicken and other unknown allergies. I occasionally try new foods one at a time mixed in with hers to see what she can handle. I bought this as a fluke for my other two because we ran out of their food by mistake. After a week of mixing it in with hers, no diarrhea or raw itchy skin! This is a miracle. To be able to switch from a $95 food to a $32 food without health consequences for her is a blessing for our family.
