Summary
About Bullmastiff
Large, powerful guardian originally bred to catch poachers, the Bullmastiff is calm, confident and deeply loyal, often bonding closely with one person. It has a short, low‑maintenance coat, needs space, consistent early training and socialisation to guide its natural protectiveness.
About Japanese Chin
The Japanese Chin is a small, fine‑boned toy companion with a silky, low‑maintenance coat and expressive, upturned face. Catlike and graceful, it bonds deeply to one person, is calm and playful indoors, needs moderate exercise, and prefers gentle handling and a peaceful home.
