While there is not much information on the Chigi breed itself, one can still learn much about the breed by studying the parent breeds. The smallest of the purebred dogs, DNA points to the Chihuahua as being descendants of the ancient Techichi dog of Mexico, a canine thought to have miraculous healing and medicinal powers. Kept by the Aztecs, these dogs were treated as regal beings - but were then cremated and buried with their owners at death. The smallest Chihuahua ever recorded was named Milly, weighing in at just one pound, and featured in the Guinness World Book of Records in 2014. Though the Chihuahua is a very tiny pet, he makes a good service and therapy dog. This breed was added to the roster of the American Kennel Club in 1904. The Corgi, according to legend, originated in the hidden sanctuaries of the Welsh fairies and were gifted to those who needed protection for their families and homes. The markings on the Corgi's fur were said to be marks from the magical saddles placed there by the elves and fairies. Indeed a fairy tale looking dog, the Welsh Corgi is a breed that truly did work the land well and were quite proficient at herding cattle and sheep. Thought to have maybe descended from Swedish cattle dogs called the Valhunds, this breed was registered with the United Kennel Club in the 1920's. The Pembroke Welsh Corgi was registered with the American Kennel Club in 1934 and the Cardigan Welsh Corgi in 1935.
