PetSmart is the top dog and the cat's meow in its industry. The #1 US specialty retailer of pet food and supplies operates more than 1,430 stores in the US, Canada, and Puerto Rico in addition to an e-commerce site. The retailer offers 11,000 products, which range from scratching posts to iguana harnesses.

Unique to PetSmart, its stores provide in-store PetsHotel boarding facilities, grooming services, and obedience training.
