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 Pyrenean Mastiff
Large Spanish livestock guardian, the Pyrenean Mastiff is a giant, steady dog with a dense white coat and dark patches. Calm, observant and deeply loyal, it’s affectionate with family yet reserved with strangers, needing space, firm but gentle training, and experienced ownership.
