what is the weight of a jack russell terrier
Jack Russell Terrier The Jack Russell should always appear balanced and alert.[32] As it is primarily a working terrier, its most important physical characteristic is its chest size, which must not be so large that it prevents the dog from entering and working in burrows.[16] The red fox is the traditional quarry of the Jack Russell terrier, so the working Jack Russell must be small enough to pursue it. Red foxes vary in size, but across the world, they average from 13–17 pounds (5.9–7.7 kg) in weight and have an average chest size of 12–14 inches (30–36 cm) at the widest part.[34]
