Australian shepherds can look similar; they can be tricolor. So can border collies. However, both of those are very active, intelligent breeds, so you'd have to be sure they fit your lifestyle! Never buy a dog based on looks alone.Health surveys of Bernese Mountain Dogs in Denmark, Britain, the United States, and Canada show that this breed is very short-lived compared to breeds of similar size and purebred dogs in general. Bernese Mountain Dogs have a median longevity of seven years in Denmark, the U.S., and Canada and eight years in the UK surveys. By comparison, most other breeds of similar size have median longevities of 10 to 11 years. The longest lived of 394 deceased Bernese Mountain Dogs in a 2004 UK survey died at 15.2 years.
Cancer is the leading cause of death for dogs in general, but Bernese Mountain Dogs have a much higher rate of fatal cancer than other breeds; in both U.S./Canada and UK surveys, nearly half of Bernese Mountain Dogs died of cancer, compared to about 27% of all dogs. Bernese Mountain Dogs are killed by a multitude of different types of cancer, including malignant histiocytosis, mast cell tumor, lymphosarcoma, fibrosarcoma, and osteosarcoma.
Bernese Mountain Dogs also have an unusually high mortality due to musculoskeletal causes. Arthritis, hip dysplasia, and cruciate ligament rupture were reported as the cause of death in 6% of Bernese Mountain Dogs in the UK study; for comparison, mortality due to musculoskeletal ailments was reported to be less than 2% for purebred dogs in general.
