The American Cocker Spaniel is a breed of sporting dog. It is a spaniel type dog that is closely related to the English Cocker Spaniel; the two breeds diverged during the 20th century due to differing breed standards in the US and the UK. In the United States, the breed is usually called the Cocker Spaniel, while elsewhere in the world, it is called the American Cocker Spaniel in order to differentiate it from its older English cousin. The word cocker is commonly held to stem from their use to hunt woodcock in England, while spaniel is thought to be derived from the type's origins in Spain.
