Happy Pets Company (HPC) is an international company that makes pet food. HPC has many manufacturing locations around the world. It sells its products to a wide variety of outlets – pet stores, grocery stores and department stores. Retailers can order products via the internet using HPC’s secure extranet, or via many other more traditional methods (e-mail, telephone, or paper orders).
HPC produces both dry and wet pet food products, including pet foods for various animals, including special products for older dogs, and for hypo-allergenic diets. It also produces pet food treats, in many different flavors and shapes. The only products that have seasonal demand are the pet food treats, which seem to sell more around holiday times.
HPC conducts research into its brands and about pet food dietary needs, and regularly updates its products, providing at least one new type of pet food every two years.
