The Jack Russell Terrier

The Jack Russell Terrier is a small, British dog breed with a white body and a double coat that can be smooth, rough, or broken. They are usually white with black, tan, or black-and-tan markings. Jack Russells are about the size of a fox, standing 13–14 in (33–36 cm) tall at the withers and weighing 13–17 lbs (6–8 kg). They have longer legs than many other terriers, which helps them chase prey on foot
