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 Neapolitan Mastiff
Ancient Italian giant guardian with massive build and heavy wrinkles. Calm and affectionate with family, wary of strangers, and protective by nature. Needs early training, steady leadership, moderate daily walks, and careful skin and drool care due to size and loose folds.
