However, their size requires owners to have ample living space and a sturdy environment. Regular exercise, a nutritious diet, and early socialization are important for keeping them healthy and well-mannered.

However, due to their protective instincts, they need early socialization to ensure they remain friendly and well-adjusted around strangers and other pets. Their large size means they need space to move, even if they are not overly energetic. Grooming is fairly easy due to their short coat, but drooling can be an issue.
