The group of dogs that are known as terriers have one thing in common - a strong urge to kill rodents and vermin. Even if they have to dig them up or go down burrows after them. They are divided into two basic groups: those with long legs and those with short legs.
The little Terrier was common on American farms during the depression, but the increased use of rat pesticides and commercial farming led to a decline in its numbers. They were maintained by a small group of breeders and slowly became more popular during the late 1970´s and 1980´s as a companion dog that will also go hunting.
The Toy Fox Terrier was recognized by the UKC in 1936, but the standard that was accepted did not allow the larger, "other" marked dogs that have become the Rat Terrier. The breed still didn´t have a written breed standard in 1994, and were frequently referred to as "Fox Terriers." This breed still has not yet been recognized by the AKC. The UKC officially recognized the breed in January of 1999. There is a Rat Terrier Club of America that is nationally recognized and promotes a written, accredited standard.
This is an intelligent, active, muscular little dog with a good disposition and medium size. It can range from 10 to 25 pounds and is 13 to 18 inches tall. They are sturdy and have high stamina with quick agile movements. When on the trail of vermin they naturally have a high, shrill bark. They are less likely to dig after the prey than other terriers, and are perfectly happy to lounge in their "owners" lap. They are extremely sensitive to their owner’s moods and to environmental changes.
This little dog thrives in a home that provides plenty of training, socialization and mental stimulation. Grooming should be minimal. This is not an "outdoor" dog, as it needs the companionship of its family.
