The only places I know of that sell Dr. Tim’s in a brick and mortar setting are select stores in Michigan and some near by states, however you can order it through chewy.com. All of those foods are available through chewy.com. However, if you do live in the Michigan area you may get lucky and have a retailer near you. The two other brands are available at speciality pet stores. You won’t find them at Petco or PetSmart.
