Sandra, most of the tricks in the video are really just variations of pivoting/spinning (clockwise and counterclockwise) - what agility people call rear end awareness. I did "perch" training stuff with him when he was a little pup to teach him that he has a butt and he has the power to move it lol.
MRL posted a really good video recently on perch training (the perch training section starts around 5:10)
Interesting! I may have to look into doing some of this. My dogs are bored with the weather and I'm looking for things to do inside too! Ridley, is an older puppy but he seems to enjoy learning new things and it really helps to calm him down since he's bursting with energy while the weather is so bad!
