Bernese Mountain Dogs are not known as excessive droolers in the realm of large breeds. Their drooling is usually confined to specific situations rather than being a constant habit. You might notice a bit more drool after they drink water, during meal times, or when they're especially excited or nervous. Compared to breeds with more pronounced jowls, Berners keep their slobber more to themselves. However, individual variation exists, and some may drool slightly more than others. Keeping a handy towel within reach for quick clean-ups can manage these drooly moments effectively. Ensuring they stay hydrated and cool, especially on hot days, can also minimize drooling. Regular checks by a veterinarian will rule out any health issues that could increase drooling. In essence, while a Bernese Mountain Dog might share a drool or two during their most joyful or anticipatory moments, they typically maintain a relatively tidy demeanor.
