The Golden Retriever is a medium-large gun dog that was bred to retrieve shot waterfowl, such as ducks and upland game birds, during hunting and shooting parties. The name 'retriever' refers to the breed's ability to retrieve shot game undamaged due to their soft mouth. The breed is a prominent participant in conformation shows for purebred dogs. The Golden Retriever is popular as a disability assistance dog, such as being a guide dog for the blind and a hearing dog for the deaf. In addition, they are trained to be a hunting dog, a detection dog, and a search and rescue participant. Because of this improvement in firearms, a need for a specialist retriever arose, as training setter and pointer breeds in retrievals was found to be ineffective. Thus, work began on the breeding of the dog to fill this much-needed role.
