Summary

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.
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.
