"Teaching your dog to lie down on cue is a great behavior to train your dog. To get started all you need is your dog, some really yummy treats to reward them with and a marker word that you're going to use to communicate when they've done the behavior correctly. I'm going to us a nice sharp ""good"" to let Jack know when he's got the behavior right.
You're going to take a little tasty treat in your hand and bring it down towards the ground, sort of between the paws, good, the minute his butt hit the ground I said the word good to let him know that that's what I wanted him to do and that's what he was getting a treat for.
So from the seated position I'm just going to drop the treat down to the ground and then say good and deliver the treat. He's following that treat down to the ground really easily so now I'm going to pretend there's a treat in my hand and I'm going to see if he'll do it without it there ,good, it looks the same as when I had the treat but now there's no treat. The treat's coming from the other hand, good.
Now I want to eventually be able to put this on a very visual cue. Dogs do really well with visual cues as opposed to verbal cues. They're visual animals or body language based animals. So now I'm going to start opening up my hand a little bit, good. And this is called refining the visual cue, eventually I want to just be able to do this and have my dog get down, good, get down to the ground. That's really great that he did that because that looked radically different than when we started. So palm down, good, and reward.
Once you feel your dog understands the visual cue, good, you can start installing your verbal cue. I like to tell people are you ready to bet your paycheck that when you give that visual cue your dog will go down? If so then you're ready to install the verbal and then you're going to say it first and then you're going to show them what it means, down, good, if they happen to just do it you're definitely going to reward them. But if they don't, down, good, you follow up the verbal cue with the visual and that way you make sure your dog gets it right every time and that's how you get your dog to lie down.
