The Jack Russell was developed by Reverend John Russell in the 1800s for fox hunting, while the Cattle Dog was bred in Australia for driving cattle; this mix combines hunting drive with herding tenacity.
Interesting Facts
Jack Russells can jump up to five times their own height; the Cattle Dog influence may add a 'nipping' instinct intended for driving livestock.
