Summary
About Chihuahua
The Chihuahua is a tiny yet sturdy companion dog, usually 1.5–3 kg with an apple-shaped head and large eyes. Found in smooth or long coats in many colors, it is devoted, alert, and bold. It needs daily walks, training, close companionship, and good health and dental care to thrive.
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.
