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 Spitz
The Japanese Spitz is a small to medium, people‑oriented companion with a pure white double coat that’s easy to maintain with regular brushing. Lively, intelligent, and trainable, it suits apartments with daily exercise. Naturally alert and vocal, it is usually friendly once introduced.
