The Mountain Feist is a small, compact, and athletic dog standing 30 to 46 cm at the shoulder and weighing 5 to 14 kg. The build is lean and muscular, designed for speed and agility in forest terrain. The coat is short, smooth, and dense. Colors include tricolor with spots, red and white, black and tan, black, and red brindle — a wide variety reflecting the breed’s mixed-breed origins. Natural bob tails and erect ears are common. The overall impression is of a small, quick, and alert working dog.
