Field Spaniel

Dog

The Field Spaniel is a medium-sized breed dog of the spaniel type. They were originally developed to be all black show dogs in the late 19th and early 20th centuries and were unpopular for work as a hunting dog. However during the mid 20th century they were redeveloped as a longer legged dog that was more suitable to be used for field work.
