I think she did good work with her pony.
But I don not think he knows thirty tricks. Alot where the same trick with a diffent name or command.
Either he had a bridle on or not. That is generally not considered a diffrent trick.
Also I think some of the shots were just lucky. She named three diffrent rears but when you watch her in the video they are pretty much what ever the horse does at that moment.
Either way thanks for posting the video it is nice to see some one spend that much time with there horse.
