The fix is a boundary stay: your dog learns that the doorway is a line he may not cross without explicit permission.
Why Traditional Corrections Don't Work
Old-school trainers used booby traps--noisemakers, long lines that flip the dog when he hits the end, startle devices. These methods rely on fear and often backfire. A determined dog learns to check whether the trap is set. And the behavior is so self-rewarding (freedom! chase! adventure!) that punishment rarely outweighs the payoff.
The solution isn't to make bolting unpleasant. It's to teach an alternative behavior that becomes automatic.
The Boundary Stay
A boundary stay means your dog will not cross the threshold--any threshold--without your release word. He sits and waits while the door opens, while guests enter, while packages are delivered. He only goes through when you say "Okay" or "Free."
This works for front doors, back doors, car doors, and crate doors. Once the concept clicks, dogs generalize it to all doorways.
How to Teach It
Step 1: Use a drag line. Attach a lightweight 4-6 foot line to your dog's collar. Let it trail on the ground while you're home. This gives you instant control--step on the line and your dog is stopped--without having to grab his collar.
Step 2: Practice at low excitement. Start with a door your dog doesn't care much about--a closet, a bathroom. Ask for a sit. Open the door a few inches. If your dog moves, close the door. Repeat until the dog holds the sit while the door opens fully.
Step 3: Add the release. When your dog can hold a sit while the door is open, add your release word. Open the door, pause, say "Okay," and let your dog through. Treat after the release.
Step 4: Increase difficulty. Move to higher-stakes doors (front door, back door). Add distractions--have someone knock, ring the doorbell, walk past. At each stage, the rule is the same: the dog sits and waits until released.
Step 5: Practice with every door opening. This is critical. The boundary stay only becomes reliable if it happens every single time anyone opens the door. Leash your dog before guests arrive. Have everyone in the household follow the same protocol.
Why Consistency Is Everything
The boundary stay fails when people get sloppy. If your dog learns that sometimes he can bolt--when the kids come home, when the delivery person rings--he'll keep testing.
Every human in the household must follow the same routine. Your dog sits before the door opens. Your dog waits until released. No exceptions.
Why This Works
You're replacing an impulsive behavior (see door -> bolt) with a trained behavior (see door -> sit and wait). The sit becomes the default response to any door opening, and the release word becomes the only trigger for going through.
Dogs who learn boundary stays are safer and calmer. The frantic door energy dissipates because there's a clear rule. Your dog knows exactly what's expected, and the guesswork is gone.
