Summary
About Mastiff
The Mastiff is a giant, heavily built guardian dog, calm and dignified yet deeply devoted to its family. It is watchful rather than aggressive, needs gentle, consistent training, moderate exercise, and space. Its short coat is easy to maintain, but drool, health care, and costs are significant.
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.
