Dog training siiiit stayyyy!!!!!! Good dog

With your dog in front of you, hold a treat in front of him, and draw it slowly over his head so that he has to look up to see it. Do not hold it so high that he will try to jump up to get it. Hold it within his reach, but keep your hand closed around it so he can’t get it.
By the time you have drawn the treat over your dog’s head, just above his eye level, he may have automatically backed up into a sit to keep his eyes on it. If so, issue a yes! and reward him.
If he didn’t sit, you can assist him into a sit by practicing this skill on leash and gently pulling it in a diagonal upward-backward direction, which will help lift his front end and encourage his back end to drop. If he successfully performs a sit, issue a yes! and reward him.
As soon as your dog learns to sit down when you hold a treat over his head, you can start to use the sit command. Issue a sit before you lure him into the position with a treat, and as he becomes proficient at it, begin to fade out the food rewards.
You can also teach him a hand signal for sit by gradually adjusting your luring motions until you are raising your fist as if you are lifting a dumbbell, or you can get in the habit of pointing to his rear end when you tell him to sit.
