A half Maltese and Japanese Spitz dog is often referred to as a Maltese-Spitz mix or a Maltese-Japanese Spitz hybrid. These mixed-breed dogs can inherit traits from both parent breeds, resulting in a variety of appearances and temperaments. They typically have a fluffy coat and a friendly disposition, making them great companions.
