Pros History


The Rat Terrier is a small and lively breed of dog that has a rich history dating back to the early 20th century. The breed was first recognized by the American Kennel Club (AKC) in 2013, but it has been a beloved companion and working dog for decades.

The breed was first developed in the United States, with the goal of creating a small, energetic dog that could be used for hunting rats and other small game. The breed's name, "Rat Terrier," is a nod to its original purpose. The breed was created by crossing various terrier breeds, including the Fox Terrier, the Manchester Terrier, and the Bull Terrier.

The Rat Terrier was a popular breed among farmers and ranchers, who valued the breed for its ability to control rat populations on their property. Additionally, the breed's small size and energetic nature made it a popular companion for families.

Historic figures such as President Theodore Roosevelt and actor Will Rogers were known to be fans of the Rat Terrier. In fact, President Roosevelt had a Rat Terrier named Skip, who was a constant companion during his time in office.

The breed's popularity began to decline in the mid-20th century, as rat poisons and other pest control methods became more widely available. However, the breed has seen a resurgence in recent years, with many people rediscovering the breed's unique qualities and versatility.

The Rat Terrier is a highly intelligent and trainable breed that excels in a variety of activities, including agility, obedience, and hunting. They are also known for their affectionate nature and make great family pets.

In addition to the AKC, the Rat Terrier is also recognized by the United Kennel Club (UKC) and the American Rat Terrier Association (ARTA). The UKC first recognized the breed in 1999.
