The Bernese Mountain Dog is very social and extremely loyal to its family, a friend for life. The Bernese is a sweet character in nature, outgoing, affectionate who loves children. Your children will love to play with this huge and friendly dog. Berners are eager to please and easy to train. They are generally good with other pets and dogs too. They may be slow to mature and remain puppy like for a while. They are very intelligent and are natural watchdogs so you can feel safe if you have a Berner watching your home. The BMD is not fit for apartments; it requires a large spacious yard in a cooler climate. They need exercise, but enjoy lounging with their owners too.
