Intake Day - unwanted behavior cannot happen without the dog’s ability to make free choices.
Then… The dogs learn by being ALLOWED to choose their old habits. This is where actual learning begins.
You can take away or redirect bad behavior, but given an opportunity, the dog will always choose THEIR preferred option. That’s simple management.
This is teaching. Want to see the meat and potatoes? It begins day one. You cannot train commands to a dog that can choose something else.
