The difference between the Russell Terrier and the native dog

1. It is a dog breed bred by a priest named Jack Russell in 1819, hence the name Jack Russell Terrier; and the native dog is the oldest native dog in China One of the dog breeds. 2. The Russell Terrier has almond-shaped eyes with darker eye circles; button ears, a flat head, and a fairly wide distance between the ears, which gradually narrows toward the eyes. The mouth has clear outlines and strong upper and lower jaws. The teeth are large and close together in a perfect scissor bite. The appearance of the native dog is closer to that of a wolf, with a pointed and short muzzle and a flat forehead; the ears are high, small and upright or semi-erect.
