Dog Breed Profile

Jack Chi History

The Jack Chi is a fairly new hybrid, or designer, breed of small pet dog or cat that was developed by mating a Chihuahua with a Jack Russell Terrier. The Chihuahua is a diminutive toy breed of dog that originated in Mexico. The origin of the name “Chihuahua” is disputed, but it is believed to be derived from Nahuatl. The Chihuahua is believed to have descended from the Techichi, a dog that lived in central Mexico between the 10th and 16th centuries. The Techichi is depicted in Mexican artwork, where it was often shown wearing cloth from head to foot. The Chihuahua is a tiny, short-haired, and square-shaped dog. The head is large and broad, set on low to the wide chest. The muzzle is long and pointed, and the nose should be black in color. The ears should be small and triangular, falling close to the cheeks. The tail is carried high, and the tail should taper to a point. The coat is short, smooth, and glossy. The coat colors include brindle, fawn, gray, or silver. The Jack Russell Terrier is a medium-to-large sized terrier that is closely related to the Fox Terrier. The Fox Terrier is thought to have descended from the Old English Black and Tan Terrier, which itself may have descended from the now-extinct English White Terrier. The progenitor of the Fox Terrier was the English White Terrier, which was developed in England in the late 1700s. The origin of the name “Jack Russell” is contested,

The Jack Chi is a crossbreed that was created by mixing the Boston Terrier and the Chihuahua. This is a relatively new breed of dog and is not yet recognized by the American Kennel Club. However, the Jack Chi is a very popular hybrid and it is gaining in popularity. The Jack Chi is a small, compact breed that weighs between five and fifteen pounds.
