Jethro's trick toolbox previously consisted of fetching a Frisbee, putting a hoop over a cone, and dribbling a soccer ball. Now, he has a new one added: lying down.
It is still a work in progress. He lays down on a blanket only right now, and weaning him off the blanket onto grass and arena footing is proving to be slightly difficult. The blanket is a very obvious, easy-to-understand location to lie down, which is why I think transitioning him to lie down without it has been a bit confusing for him (considering how he sees and walks on grass everyday). He lies down on the grass directly near the blanket, but never without the blanket present.
It has been taught purely through association and positive reinforcement/clicker training only. When I was first looking through tutorials, most of them involved ropes and pulling/pushing. I knew he wouldn't like that very much, so I cast those tutorials aside and figured out a more suitable method. Personally, I don't really see the point in trick training if you force the animal to do the trick. I view it as a fun break from regular training, and something they should look forward too (via positive reinforcement, not force). He learned his other tricks within three 15 minutes a day sessions. This one has been a bit more difficult. I have done three 15 minutes a day sessions so far and am anticipating several more days until he has it nailed down without a blanket.
We will work through it though! As soon as everything is ironed out and consistently problem free I will write up a post with the details of how I taught the trick.
