Established in 1988. Pet Supplies Plus was started in 1988 in Redford, Michigan. There are over 400 stores in more than 30 states, with more than half of them being individually owned and operated.The chains founders, Harry Shallop and Jack Berry had a terrific idea. They wanted to bring supermarket-style convenience and value to the pet food and supply industry. By building stores in local neighborhoods with smaller footprints, Jack and Harry made it easier for our neighbors to shop. Over the years, their ideals have served us well. Which is why, as we look to grow in the future, we will continue to provide our neighbors with the easiest shopping experience to help them better care for their pets.
