Friendly, alert, courageous, sometimes stubborn. Excellent with families. Strong prey drive.
60 minutes of daily exercise plus play.
Weather-resistant double coat. Hand-strip every 8–10 weeks; weekly brush.
Globoid cell leukodystrophy (DNA test). Patellar luxation. Allergies.
Full Cairn Terrier profile →Bold, energetic, alert, independent. Jack Russells are famously feisty — they don't back down from larger dogs and are determined hunters of small animals. Loyal but not endlessly cuddly.
60–90 minutes of vigorous daily activity. They thrive on agility, terrier racing (terrier-go), flyball and hide-and-seek games. Without enough exercise they dig, bark, escape.
Three coat types: smooth (weekly brush), broken (twice a week + occasional hand-strip), and rough (weekly + regular hand-stripping). All are low-maintenance compared to long-coated breeds.
Generally extremely healthy and long-lived (often 15+). Watch for: patellar luxation, lens luxation, deafness in some white-headed lines, Legg-Calvé-Perthes (small breeds).
Full Jack Russell Terrier profile →Active families, country / suburban homes.
Active singles, country homes, sport handlers, owners who can be firm and patient.
