I have been competing in agility for several years now and I voice the same concerns as Kyllobernese. Even though my dog can jump some incredible heights, I don't jump her at those heights as the long term effect on her joints would be terrible. Your dog looks like she would make a great agility dog. But I have to tell you, in all honesty, I was cringing when I saw your video. Please get some training with a good trainer, one who competes in agility. There is A LOT more to agility than just jumping over poles. It is a great sport and you will have a blast. It looks like you and your dog have a great time....with some good training, you will make a great team.
