Founded in 1986 by Jim and Janice Dougherty, the company opened its first two stores in 1987 in Phoenix, Arizona under the name PetFood Warehouse, as warehouse-type stores that sold pet food in bulk at discount prices. Under new leadership the company changed its name to PETsMART in 1989 and, along with expanding around the country, began a longterm shift away from visually unappealing discount warehouse stores to attractive stores that sold pet food and supplies and offered services such as grooming, adoption events, and vet visits. The company went public via an IPO in 1993, and thereafter increased its nationwide expansion and the types of goods and services it offered.
