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. Organizations covering groups of breeds 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. Other types of animal associations 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.
