MethodPositive reinforcement
Challenges

Bernese Mountain Dog Considerations
challengeSeparation Anxiety ("Velcro Dog" Syndrome)
The BMD was bred to work closely alongside farmers in the Swiss Alps, pulling carts and driving cattle. This history has created a breed that is genetically wired to be near their humans constantly. They are not independent yard dogs; they are "shadows." Leaving a Berner alone for 8+ hours a day often results in severe distress, destructive chewing, and vocalization.
challengeThe "Leaner"
While affectionate, their desire for physical contact (leaning their 100lb body weight against your legs) can be a hazard for elderly owners or very small children, despite their gentle intent.
