For example if he wants food he has to remain seated until you make his dinner, or if you want to talk him for a walk then he has to lie down until you put his leash and collar on.
These training techniques all are based on the fact that your dog will realize to get what he wants he has to do what you are telling him to do.
What if he doesn’t do it?…
Walk away.
Don’t shout at him or keep trying if he doesn’t listen just ignore him and walk away then about 5 minutes later go back and try again.
He soon comes to realize that you are in charge and he has to do what you say to get what wants.
