The company who makes Authority dog food is called Authority, Inc. Authority brand dog food is sold exclusively at PetSmart, and was first founded as a company in 1995. They market their food as being “nutrient dense” and high in protein. have had my dog on Authority Chicken & Rice Dry Dog food for 3 years now. I am very pleased with the food. She loves it and is a very picky dog. I tried to switch her over to a higher priced food to see if it really makes a difference, she would not take to it at all.
