Summary
About Tosa
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.
About Leonberger
Large, strongly built “gentle giant” with lion‑coloured, water‑resistant double coat and black mask. Typically calm, devoted, and very good with children and other pets when well socialised. Needs regular exercise, kind training, thorough grooming, and careful health management.
