Here's a link to Lucky's video. This was in the middle of his training class - he's a bit more proficient at some of the tricks now and we forgot to do the a few like jumping over my legs, army crawl etc. But maybe it will inspire you!
Today Luke worked on putting his back feet on a box. He loves to do stuff with boxes. He can go in the box, all 4 feet on the box, front 2 feet on the box, and now he did back feet on the box. I hope this will help him in agility, to do his contacts. He can run across the room over the box and end with his back feet on it. He can also back onto it with his back feet if he's not far from it. All of the stuff he does with the box are from something called 101 things to do with a box. If you google it, you'll find lots of links on it, but this one just happens to have other ideas on the bottom of the page.
I'd like to train Luke to do a hand stand, though I don't know if he can do it. If I wanted to do it, I can put his box against the wall, and then start angling it up.
I enjoy trick training so it's nice to see some inspiration here!
Thought I'd add http://www.youtube.com/watch?v=5jo6BVt9cnU . It's a papillon, not a cavalier, but impressive! I'd love to teach my dogs even half of what this little guy can do.
My favourite trick with Drake (my brainiac) at the moment is his "High Five!" It was pretty easy to train, holding a treat between my middle and ring fingers and letting him investigate it with his nose, clicking and treating when he started to reach for it with his paw, gradually waiting a bit longer to give him the treat until his pad slapped firmly against my palm. I was so happy and excited at his little cool dog trick that I think it's rapidly become my favourite thing - he knows it, every time I ask him for a high five I get it instantly, and still squeal with delight every time :D
