They carry a variety of pet food my beagle has allergies so we avoid the more domesticated type like beef chicken etc and I think the food we get them now helps it for sensitive skin and stomachs the staff is super friendly and they adopt out rescued animals so they don’t stock animals like a pet store which I like a lot I’m a firm believer in adopting rescues. I’m happy they rescue animals and are located in a convenient place over all a great place ^.^
