Backyard breeder

A backyard breeder is an amateur animal breeder whose breeding is considered substandard, with little or misguided effort towards ethical, selective breeding. Unlike puppy mills and other animal mill operations, backyard breeders breed on a small scale, usually at home with their own pets (hence the "backyard" description), and may be motivated by things such as monetary profit, curiosity, to gain new pets, or to show children "the miracle of birth".
A backyard breeder is often a substandard breeder of dogs and horses, and the term is used in this sense by the Animal Welfare community, The American Society for the Prevention of Cruelty to Animals (ASPCA), larger established breeders and breed clubs in contrast to the more positive term, "reputable breeder" that describes operations that use responsible methodology and practices.
It implies either or both of home breeding for non-commercial reasons or a for-profit small commercial operation that does not adhere to good breeding, care and sale practices. Larger commercial operations of a similar type that breed dogs are usually termed a "puppy mill" (especially in North America) or "puppy farm". However, as large kennels usually require licensing, many puppy mills are licensed with the USDA.
Many small breeders resent the term and its use. Some do so because they assert that they run small but high-quality "boutique" operations. Others argue that their unregistered animals are desirable as companion animals and economical for ordinary people to purchase. Both groups deny that they contribute to low quality within the registered breed or produce unwanted animals.
Undesirable characteristics.
This type of breeder is usually regarded by the Animal Welfare, ASPCA, and other groups as likely to exhibit one or more of the following characteristics:
With horses, the USA horse slaughter issue is closely linked to backyard breeding, as many poorly bred, unregistered horses have no value other than to horsemeat buyers.
Opposition to.
There are campaigns to reduce or eliminate this type of breeding in several countries as well as video campaigns by groups like ASPCA that emphasize the importance of understanding the responsibilities associated with owning an animal. The primary concern of the Animal Welfare community is that this type of breeding is the major source of pet animals and that overproduction has led to overpopulation and hence to welfare issues and the putting down of animals for no other reason than the lack of suitable home. The glamorization of Chihuahuas, which some claim has been generated by Hollywood, has had devastating outcomes for dogs and their adopted owners. Specifically, dog owners like Paris Hilton and commercial-star Gidget the Taco Bell chihuahua as well as films like Beverly Hills Chihuahua have been directly cited as blameworthy. Most dog breed societies and Kennel Clubs have similar concerns but place rather more stress on issues relating to breed standardization and quality.
There are many animal adoption alternatives that potential pet owners can consider, including animal shelters and the umbrella organization The Shelter Pet Project, animal rescue groups, online organizations such as Petfinder that directly connect prospective adopters with available animals, and print media such as local newspapers.
