Bernese mountain dogs have good temperaments and are generally well-suited to life as family pets. However, they can be very large and energetic, so they need a lot of exercise and training to be safe around small children.
Another drawback of Bernese mountain dogs as family pets is that they do not live very long and are prone to many genetic health problems. They are susceptible to malignant histiocytosis, which is a dangerous cancer that is difficult to cure. It is important to get a Bernese mountain dog from a good breeder to avoid these conditions. This breed can also be shy and needs a lot of early socialization to remain friendly and safe around strangers.
