Breed History: 

The Jack Russell Terrier traces its origins to early 19th‐century Devonshire, England, when Reverend John Russell set out to breed terriers specifically for fox hunting. In 1819, he acquired a white female terrier named Trump, whose traits formed the basis for his line of agile, determined hunting dogs. Bred to flush foxes from their dens without harming them, these compact and flexible dogs quickly gained a reputation for intelligence and tenacity. Over the decades, while various strains evolved—including the longer-legged Parson Russell Terrier—the original working spirit of the Jack Russell has endured.

Breed Appearance: 

Jack Russell Terriers are predominantly white, accented by distinctive black, brown, or tan markings. Their coat may be smooth, rough, or a combination of both. These dogs possess a well-proportioned head that is moderately wide at the ears, tapering gracefully toward lively, almond-shaped eyes. The transition between the muzzle and the head features a subtle stop, emphasising a strong, well-boned jaw with a scissor bite and straight teeth. They typically have a black nose and small, V-shaped ears that point forward. 

Breed Type - Family/guard: 

As family dogs, Jack Russells are energetic, intelligent, and playful companions that thrive in active households. With proper exercise and socialisation, they bond well with family members, offering affection and lively entertainment.

As guard dogs, these terriers may be small, but their fearless, alert, and vocal nature makes them excellent watchdogs. Bred for fox hunting, they possess a keen sense of their surroundings and will promptly signal any unusual activity.

Smart but strong-willed:

• Highly intelligent and quick to learn
