A pet store is classified as a store that specifically sells pet products. There are a number of department stores or other retail stores that carry pet products; however, they are not classified as a pet store. These locations are known as only having a pet department. Depending on the type of retail store in question many retail stores with a pet department only carry the most needed items including pet food or bedding. While traditional retail stores with a pet department are a great way to get pet supplies when already shopping in the store, many pet owners find it more convenient to shop directly at a pet store.

There are a number of reasons why a pet owner would prefer to shop at a pet store and the most common reason is due to the selection of products available. Most pet stores are a fairly decent size and they tend to carry everyday pet items and other special items. In addition to pet supplies, it is also likely that a pet store may be selling a selection of pets. It is not uncommon to find fish, cats, dogs, hamsters, and other small animals on display at a pet store.
