so i should get a long check cord and let her go to the end or whatever and call her name and if she comes back pet her real good but if she ignores me then give it a quick tug on the cord and call her then continue that if she dosnt listen?
That's the gist of it. Your goal is to set your dog up to win, not to fail. Let him wander off while attached to the cord, then tell him to come, and reel him in, and praise him for it. Another thing you can do......two people sit in a room with treats. Take turns calling the dog back and forth between you, giving the dog treats and praise each time. The dog will figure out real quick to just go back and forth from person to person to get treats, so the key is to not give the dog a treat unless you actually called him. You have to be on the ball and call him before he starts heading your way. If he comes before you call him, ignore him and have the other person call him. You're trying to build the brain connection that "come"=good things, not just that running up to you=good things. Eventually you can do it from different rooms and floors of the house and add in distractions, too.
If your dog happens to run away.....don't call his name 5000 times, youll just teach him to ignore you. When you eventually catch him, shower him with praise, no matter how frustrated you are. Dogs don't really think about the past or the present. If you punish your dog once you catch him, he won't connect the running away with the punishment, he'll just connect coming to you on his own with the punishment. If you shower him with praise, then he'll connect coming to you on his own with good things. Try to catch him without calling him. For example, when our dogs were young puppies, if they happened to get out I would try to avoid telling them to come, but they'd jump into an open car door, or fetch a stick and bring it back, and i could catch them that way. Anything to make them come to you without calling them 5000 times. It's not ideal, because the dog can connect running out the door with an on-demand car ride or whatever, but if your dog gets out you're past the point of what's ideal and you're just trying to make the best of a less than ideal thing.
