Behavioural problems occur when we lead our dogs with emotion. We overthink every little thing, try to rationalize their behaviour, plead with them, talk to them like they are human, use their histories or stories as an (unintentionally self-serving) excuse to treat them like humans, instead of simply meeting their current canine needs: Exercise, Discipline (boundaries), then Affection.
It's not until we learn to lead instinctively, with our energy instead of emotion, that our dogs start to follow and respect us.
Dogs are actually very simple. That's why my best clients to teach are children. They are still very connected to their instincts and energy.
