It does take a lot of training to do something like that with a dog. I know, I did stuff like that with my dog TinyMonsters (a Bouvier des Flandres, he died 2yrs ago this month)

We never did do stuff as intricate as that girl and her dog (an australian shepherd?) did in that video tho. Mostly it was stuff to get Tiny to heel with me better, but we did a lot of the same stuff she was doing in that video.

I miss my dog now...watching that video made me remember all the training we did. Tiny was such a goofball on training days.
