Breeders, pet shops, and animal care facilities are all common animal-related businesses that require specific business licenses by states, counties, and cities. The primary goals of these business licenses are to ensure that animals are properly cared for and treated humanely. State officers inspect facilities regularly as a condition of licensure.
Most states require some type of business license for manufacturers and distributors of commercial feed and pet food. This is usually regulated by the State Department of Agriculture. The state will either require a license for the business that makes the food or registration of the packaging labels. A license is often required for each location where the commercial feed is produced.
