25–27.5 in (64–70 cm) for males, while it is 23–26 in (58–66 cm) for females. Weight is 80–120 lb (35–55 kg) for males, while it is 75–100 lb (35–45 kg) for females. The Bernese Mountain Dog (German: Berner Sennenhund) is a large-sized breed of dog, one of the four breeds of Sennenhund-type dogs from the Swiss Alps. Owners of Bernese Mountain Dogs are nearly three times as likely as owners of other breeds to report musculoskeletal problems in their dogs; the most commonly reported being cruciate ligament rupture, arthritis (especially in shoulders and elbows), hip dysplasia, and osteochondritis. The age at onset for musculoskeletal problems is also unusually low. In the U.S./Canada study, 11% of living dogs had arthritis at an average age of 4.3 years.
