American Breeder is an online marketplace and resource hub for people seeking animals, pet-related products, and services. It brings together breeders, vendors, and prospective buyers, with classified advertisements for animals across a broad range of categories. Listings cover dogs and cats, birds, rabbits, livestock, rodents, reptiles, amphibians, aquarium fish and invertebrates, arachnids, insects, and exotic pets. Visitors can browse by animal type and, where available, by breed or group.

The site supports both breeder and vendor advertising, offering breeders six-month ad placements for $6 and vendors advertising for a $15 fee plus pay-per-click costs. Users can register, log in, submit testimonials, request a breed listing, and access adoption services. American Breeder also provides educational and promotional resources, including quickstart guides, video guides, a resource library, blog posts, events, and a glossary. Its featured articles include guidance on raising newborn puppies. With its searchable categories, marketplace listings, and support materials, the platform aims to connect animal sellers and buyers while helping users learn about breeds and responsible pet care.
