History
The Jack Russell Terrier originated in the early 1800s, bred by Reverend John Russell for fox hunting. Valued for speed, courage, and a strong prey drive, the breed became a favorite among hunters for its ability to chase quarry underground. By the 20th century, Jack Russells gained popularity in the US as energetic companions and agility stars. Today, they remain one of America’s most spirited and capable small working terriers.
