Every dog breed has its own traits, type of coat, exercise needs, and other things. Japanese dog breeds are not an exception to this rule. Japanese dog breeds have similar needs; however, they are not the same. For example, most Japanese dogs have thick double coats, prick ears and make excellent guard dogs. While some are hunting dogs, other Japanese dog breeds are meant to be guard dogs. You will find a Japanese dog that’s a good companion dog or guard dog.
