The Decker Hunting Terrier (Decker Terrier, Decker Rat Terrier, Decker Giant) is a comparatively young breed. The breed was developed in the United States in the 1970's, by a breeder named Milton Decker. The Decker hunting terrier was derived mainly from the Rat Terrier, however, Feist, Basenji and Fox Terrier were also instrumental in the breed’s development. The Decker Hunting Terrier was developed as a functional hunting dog, and is used on a wide variety of game. They are commonly used for flushing game birds, rabbit, and deer. They have also been used by sportsmen as tree dogs, primarily for raccoon and squirrel.

General Appearance
The Decker Hunting Terrier is first and foremost a hunting and sporting dog, and should be in hard muscular condition. They have a regal appearance and carry themselves with confidence. They are a small to medium hunting terrier, and are slightly longer (from prosternum to point of buttocks) than tall (from withers to ground). Individuals should stand true over the feet, and the length of leg is proportionate to the rest of the body. The head is broad, wedge-shaped, and proportionate to the size of the body. The tail is set fairly high, and is carried proudly. Decker Hunting Terriers may have a full natural tail, a docked tail, or a natural bobtail. The tail posture while the dog is working will be wayward, and is not important. The coat is short and smooth. The Decker Hunting Terrier comes in white with colored patches, or solid colored, with or without white markings.

This breed is a clever, determined, fearless hunter when in the field. They hunt by sight, use winding ability, and will follow a hot track, but are not a cold nosed dog. They are virtually silent while tracking, but may have a “pursuit yip” when on an extremely hot track, or running by sight. When treed, the voice may range from whining, to a choppy bark, to a “scream”. When not hunting, the Decker Hunting Terrier is a friendly companion, and enjoys human companionship immensely; they will enthusiastically share any activity with their owners. They are energetic and alert, their intelligence makes them easy to train.
