Parson Russell Terrier vs Tosa

Parson Russell Terriers are medium‑small, long‑legged, athletic fox‑hunting terriers with smooth or broken white coats. Energetic, intelligent, bold, and affectionate, they need plenty of exercise, consistent training, mental stimulation, and clear boundaries in an active home.

The Tosa is a large, powerful Japanese breed, calm and dignified at home yet naturally protective. Loyal and often devoted to one person, it needs experienced handling, early socialisation and consistent training. Short-coated but high-commitment, it faces legal restrictions in some countries.
