Feist (dog)
Feists are small to medium-sized dogs 10 to 18 in (45 cm) tall, and weigh 15 to 30 lb, short-coated dogs with long legs. The ears are set high on the head and are button, erect, or short hang. The tail can be natural, bobtail, or docked. As feists are bred for hunting, not as show dogs, little to no consistency is seen in appearance (breed type), and they may be purebred, crossbred, or mixed-breed dogs. They are identified more by the way they hunt and their size than by their appearance.
