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. American breeders of Golden Retrievers sometimes import their dogs from Britain to take advantage of the temperament and appearance of the British types. The Golden Retriever's eagerness to please has made it a consistent, top performer in the obedience and agility rings. Its excellent swimming ability makes it proficient at dock jumping. A natural retrieving ability means it is also competitive in flyball and field trials.
