A calm dog at the door isn’t just a nice-to-have—it’s the foundation of a safe, predictable home environment. When a dog learns to regulate their excitement in that high‑energy moment, they’re practicing impulse control in one of the most challenging contexts. That single skill ripples outward into better behavior everywhere else: fewer frantic greetings, less jumping, and a dog who can actually think instead of reacting on pure adrenaline. It’s the difference between chaos and clarity, and it starts before the doorknob even turns.
