I hear the same sentence two or three times a week, usually on a first phone call: he knows it, he's just being stubborn. Almost every time, the dog doesn't know it. He knows a version of it that exists in one room, with one person, holding one bag of treats.
That isn't a character flaw. It's how dogs learn. A dog attaches a behavior to the whole picture in front of him — the floor under his feet, the light, your posture, what he expects to happen next. Change the picture and you have, from his side of it, changed the question.
A room is not the world
A sit taught in a quiet kitchen is a kitchen sit. It's real, it's just narrow. Take that same dog to a trail with wind, other dogs and something dead in the grass forty feet off, and you're asking a question he has never been asked before. He isn't refusing. He's guessing.
Every command has a price, and the price is whatever the dog gives up to do it. At home the price is nothing. At the park the price is a squirrel, three dogs and a kid with a sandwich.
If the price goes up and the training doesn't, the command loses. That's not disobedience. That's arithmetic.
Distraction gets added on purpose
Proofing means taking a behavior the dog already performs cleanly and rehearsing it somewhere slightly harder — one variable at a time.
The order I work in, roughly:
- Distance. Can he hold it when I step away, then walk away, then leave the room?
- Duration. Thirty seconds, then two minutes, then five.
- Distraction. A ball rolling past, then a dog at forty feet, then a dog at fifteen.
Only one of those moves at a time. If I add distance, distraction stays where it was. If he fails twice in a row, I moved too fast and I go back a step. Nothing about that is dramatic and nothing about it is a correction.
Most stubborn dogs are under-proofed
The parking lot at the feed store teaches more than my field does. So does your own front yard at five o'clock. Your living room stopped teaching your dog anything weeks ago.
Ten minutes a day, somewhere new, with a behavior he already has. Do that for a month and the sentence changes. It stops being "he knows it at home" and starts being "he does it anywhere." There's no shortcut through that part.
