About the Decker Rat Terrier
The Decker Rat Terrier is a larger strain of the American Rat Terrier developed by breeder Milton Decker to produce a bigger, more robust hunting and companion dog. Standing taller and heavier than the standard Rat Terrier, Deckers retain the breed's keen intelligence, high prey drive, and versatile working ability. Their short, smooth coat is easy to maintain and commonly appears in bicolor or tricolor patterns with white markings. Loyal, energetic, and highly trainable, the Decker bonds strongly with its family and can be protective, making it an alert watchdog. This active dog suits owners who can provide plenty of exercise and structure.
Every dog is an individual — genetics, socialization, health, training, and environment matter more than breed averages.

History
The Decker Rat Terrier emerged in the United States when Milton Decker sought to develop a larger, hardier line within the Rat Terrier breed during the mid-20th century, sometimes said to include larger crosses to increase size. These dogs were prized for hunting larger game and for their courage and stamina. The strain is recognized within Rat Terrier registries such as the United Kennel Club rather than as a wholly separate breed.
Temperament
Deckers are intelligent, loyal, and energetic, forming devoted attachments to their people and often bonding strongly with one family. They are alert and can be protective, which makes them capable watchdogs, and they possess a strong prey drive toward small animals. With consistent training and socialization they are highly responsive and eager working partners.
Questions to ask a Decker Rat Terrier breeder

Health considerations to discuss
Patellar luxation. A knee issue seen in terrier types; ask about parental screening.
Hip dysplasia. More relevant in the larger Decker size; hip evaluation is worthwhile.
