Breed clubs are associations or clubs with activities centered on a single, specific breed of a particular species of domesticated animal. The purpose of the association will vary with the species of animal and the goals and needs of the members of the association. Breed associations or clubs may vary in their goals, activities and nomenclature from country to country, even for the same breed. Most domesticated animals, whether they are agricultural animals such as cattle, llamas, poultry, sheep and pigs, or companion animals such as pigeons, horses, cats and dogs, have breed clubs associated with the breed.
In general, breed clubs and associations create a written definition of the breed (called a breed standard) for the breed with which the organization is associated. Breed clubs also maintain important records, and provide members with information. Many breed associations also have a social component, organising various activities such as shows. In addition, they may regulate breeding or raise funds for research related to the breed.
With the advent of the internet, anyone can create a "breed club" by putting up a web page to advertise their animals. Buyers must research any claims of unaffiliated breed clubs.
Breeds of animals of a particular species may have an organization that covers a large number of breeds of the species, even though each individual breed may have its own breed club. Often the multiple-breed over-association will maintain the breed records in a central location. An example of this would be the Canadian Sheep Breeder's Association, incorporated under the Canadian Livestock Pedigree Act in 1915, which includes fifty different breeds of sheep.[9]
Associations that include all breeds (as well as crossbred and mixed breed animals) of a particular species also exist. Usually such associations are organized for particular sports, such as hunting with raptors.
