The Decker Terrier
Characteristics of This Unique Rat Terrier Breed
The Decker Terrier is a remarkable and rare branch of the Rat Terrier family, admired for its size, versatility, and loyal temperament. Sometimes referred to as the “Decker Giant Rat Terrier,” this breed was developed in the 1970s by Milton Decker with the goal of creating a dog that was larger, athletic, and adaptable while still retaining the intelligence and loyalty of the traditional Rat Terrier.
Today, the Decker Terrier is known as a loyal companion, excellent family dog, and versatile working partner — making it one of the most sought-after Rat Terrier variations.

Size and Build
One of the first things people notice about the Decker Terrier is its impressive size compared to standard Rat Terriers.
- Height: Typically, 18–23 inches at the shoulder
- Weight: 25–40 pounds on average
- Build: Muscular, athletic, and well-proportioned with a sleek, powerful frame
This larger size makes the Decker Terrier sturdier for families with children and better suited for active lifestyles. They are commonly seen with some face wrinkles and possess a very regal elegance, which has been fondly dubbed the “look” of the Decker Terrier.
A Decker Terrier’s ears should be erect and held high on their head, however there are dogs that have tipped ears. Milton Decker paid very close attention to those ears and set that trait in with good stability.
Temperament and Personality
The Decker Terrier is more than just an athletic dog — it’s a devoted and loving member of the family.
- Affectionate: Deckers bond closely with their families and thrive on companionship.
- Confident: They’re bold without being aggressive, making them excellent watchdogs and loyal protectors.
- Quiet: They are not “yappy” like most terriers tend to be, making them suitable for close quarters living.
- Intelligent: Highly trainable and eager to please, Decker Terriers excel in obedience, agility, and interactive games.
- Adventurous: They love outdoor activities like hiking, running, or simply playing in the yard.
This unique balance of energy and loyalty makes them a wonderful choice for both active singles and families with children.
Abilities and Instincts
Bred originally as hunters, the Decker Terrier still carries strong working instincts today.
- Natural Hunters: Skilled at tracking and eliminating pests such as squirrels, rabbits, and rodents.
- Athletes at Heart: Agile and quick, they excel in dog sports and thrive with physical activity.
- Problem Solvers: Their intelligence allows them to learn tasks quickly and adapt to new environments with ease.
These qualities make the Decker Rat Terrier versatile — equally capable as a hunting partner or a playful family dog. There are quite a few people who enjoy doing dock diving with their Deckers.
Care and Lifestyle Needs
Owning a Decker Terrier comes with the joy of having an energetic, loyal companion, but they do best with families who can meet their needs:
- Exercise: At least an hour of daily activity is ideal to keep them healthy and happy.
- Training: Consistent, positive reinforcement works best with their intelligent and eager-to-please nature.
- Socialization: Early socialization ensures they grow into well-mannered and confident adults.
Deckers adapt well to both country and suburban living, as long as they have enough exercise and companionship.
