Tosa

Dog breed profile

The Tosa, also known as the Japanese Mastiff, is a giant breed developed in Japan for strength and courage. It has a calm and reserved temperament but can be protective of its family. This breed requires consistent training and early socialization to thrive as a companion. Due to its size and temperament, the Tosa is best suited for experienced owners with ample space. Grooming needs are minimal thanks to its short coat, and regular exercise is necessary to keep it healthy and happy. While the Tosa can be loyal and affectionate, it may be wary of strangers and other pets, so proper introductions are important.
