CHOW CHOW. A powerful, sturdy dog of Arctic type, medium in size and muscular with heavy bone, the Chow Chow is an ancient breed of northern Chinese origin. While the breed was originally a working dog, he primarily serves as a companion today and is seen in show rings across the country. The true origin of the Chow is unknown, but the breed as it is known today is easily recognizable in pottery and sculptures of the Chinese Han Dynasty (206 B.C. to 22 A.D.). An all-purpose dog used for hunting, herding, pulling and protection of the home, some scholars claim the Chow was the original ancestor of the Samoyed, Norwegian Elkhound, Pomeranian and Keeshond.
