Pulling isn't a strength problem. It's a leadership and communication problem.
Your dog isn't pulling because they're stronger than you. They're pulling because somewhere along the way, they learned the contract: forward equals go. Tight leash works. Drag the human, get to the squirrel, the bush, the other dog. Every successful pull confirms the system.
The fix isn't a stronger arm or a tougher harness. It's retraining the contract. Tight leash means stop. Loose leash means we move. The dog learns that they control the walk by giving you slack — and that "interesting things happen" only when the leash is loose.
This matters most when seeing other dogs, which is the #1 trigger we get called about. Even if your dog is friendly, a hard pull toward another dog is risky — that other dog might not be friendly, and a 70-pound dog who breaks loose can run into traffic or get attacked. The injury risk runs both directions.
We do the work where the pulling actually happens — in front of your house, on your block, on your route. By the end, you've got loose-leash walks that hold up in the real world, and the walk goes back to being a break instead of a daily fight.
