The difference between Russell Terrier and native dog A minute to teach you to easily distinguish

The difference between the Russell Terrier and the Earth Dog 1. is a breed bred by a priest named Jack Russell in 1819, hence the name Jack Russell Terrier; while the Earth Dog is one of the oldest dog breeds native to China. 2. the Russell Terrier has almond-shaped eyes with dark circles; button ears, a flat skull, and fairly widely spaced ears that gradually narrow toward the eyes. The mouth is well defined and the upper and lower jaws are very strong. The teeth are large and close together, with a perfect clipped bite. The native dog is closer to the wolf in appearance, with a pointed, short mouth and flat forehead; the ear position is high and the ears are small and erect or semi-erect.
