About Rat Terriers

With all the traditional characteristics of a typical terrier — loyal, tenacious and fun — the Rat Terrier makes a great family pet, provided they are properly socialized, trained consistently and provided with plenty of attention and mental stimulation to prevent boredom.

Origin: United States

Terrier Group

These are feisty, energetic dogs whose sizes range from fairly small, as in the Norfolk, Cairn or West Highland White Terrier, to the grand Airedale Terrier. People familiar with this Group invariably comment on the distinctive terrier personality. Terriers typically have little tolerance for other animals, including other dogs. Their ancestors were bred to hunt and kill vermin. Many continue to project the attitude that they're always eager for a spirited argument.

Rat Terrier Appearance

Rat Terriers are found in two sizes — miniature (10 to 13 inches in height) and standard (over 13 inches, not to exceed 18 inches in height). They have a smooth coat that comes in multiple patterns and color variations.

History

Bred by combining the Fox Terrier, Manchester Terrier and the now-extinct Old English White Terrier, the Rat Terrier was bred to catch and kill rodents in Europe to help control the plague. The earliest ancestors of the breed made their way to America in the 1920’s and became a multi-purpose farm dog, not only helping with rodent control but also hunting small game, says Kallas. “As farmers began using modern-day ways of controlling their rodent problems, the Rat Terrier became less popular, and by the 1970s it wasn’t as commonplace on farm,” she adds. A handful of enthusiastic breeders have kept the breed going since then, creating different types based on the jobs they needed the breed to perform.
