In 1986, PetSmart founders, Jim and Janice Dougherty had an idea about starting a pet superstore. After securing a venture capital loan, they opened two stores in Arizona called PetFood Warehouse. In 1989, they changed the name to PetSmart and had expanded to 12 stores. They went public in 1993 and trades on the NASDAQ stock exchange under the symbol of PETM. Today they have over 1,232 retail stores in the U.S., Canada and Puerto Rico.
