Summary
About Shih Tzu
Small, sturdy companion dog from Tibetan and Chinese palaces, 4.5–8 kg with a long, flowing coat and chrysanthemum-like face. Affectionate, cheerful, and confident, it suits many homes. Needs moderate exercise, intensive grooming, and patient, reward-based training.
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.
