They also enjoy a good romp in a safe open area off leash, such as a large, fenced yard. Papillons are a very active breed of dog and enjoy having a job to perform. Papillon breeders recommend dog agility, rally obedience, or obedience training for Papillons because of their intelligence and energy level. The name Squirrel Spaniel also has been used, most likely referring to an earlier standard in which the tail set is described as 'curling over the back as a squirrel's'.
