The Bernese mountain dog is a friendly breed that takes to training easily. According to the AKC, this “gentle giant” is mild-tempered and loves outdoor activities. This breed needs a moderate level of exercise, which will usually keep your dog from barking or acting out.
The Bernese Mountain Dog Club reports that “with the training essential for ownership of a large working breed, Berners are generally gentle, easygoing, and tolerant.” But they do need plenty of interaction with people. And the club advises training should always use positive techniques.
