With weights of up to 115 pounds and standing between 23 and 27 inches at the shoulder, Bernese mountain dogs are the second largest of the Sennehunds. Only the Greater Swiss mountain dog is larger, while the Appenzeller mountain dogs and the Entlebucher mountain dogs are smaller. Bernese mountain dogs are also further distinguished from the other breeds by their coat as they are the only ones of the four to have long hair.

As we mentioned earlier, Bernese mountain dogs are the only Sennehund to have a long coat. In fact, they are renowned for their thick and silky coat which provides them with plenty of protection from the harsh mountain weather. This is because they have a double-layered coat. Dogs with a double-layer coat have a shorter cycle of hair growth than those with a single-layer coat. This results in them shedding all year round. However, although Bernese mountain dogs shed all year, they still shed more heavily twice a year – in the spring and the fall.

Unfortunately, the downside to owning a Bernese mountain dog is that it has a fairly short lifespan. Although many other dog breeds have a life expectancy that exceeds 10 years, Bernese mountain dogs only have a life expectancy of 6 to 8 years. Sadly, this short lifespan is because they often develop some health problems, with cancer being one of the most common. Other problems include hip and elbow dysplasia and various eye conditions.

For centuries, Bernese mountain dogs have worked tirelessly alongside their owners on farms, and even today their main role is to guard livestock. With their calm yet independent nature, these dogs are perfect for the job and take on their duties. In many cases, the dog lives with the livestock and patrols the fence line where they fend off predators such as stray dogs and wolves. Quite often, they even develop a bond with their flock of sheep or herd of goats or cattle as they are so dedicated to their job.

All puppies are incredibly cute and adorable, especially when they’re still in that goofy, playful stage. Bernese mountain dogs are no exception, but owners of them get to enjoy that playful puppy stage for a bit longer. This is because Bernese mountain dogs are actually really slow to mature. They don’t reach their full adult size until they are 2 to 3 years old and – just like their bodies – it takes them a while to mature mentally. This means that as working dogs, it takes time for them to fully settle down and be mature enough to learn to work.
8. Bernese Mountain Dogs are Always Tricolor

One of the inevitable things about owning a dog is having to deal with drool. However, despite their large jowls, Bernese mountain dogs don’t actually drool more than other dogs. This is because they are a dry-mouthed dog breed. But that’s not to say that they don’t drool at all, because they do. It simply depends on the individual dog, the size and position of their lips as to just how much they actually slobber.
