You can see the trick as part of a freestyle routine at 1:15 in the following clip. For this challenge all that is required is for the dog to move into the stand tall position back to back with the trainer, there is no walking required and minimal duration. As an alternative if you think it is better for your dog you can teach it as a sit up and beg back to back with you. To participate you can have already either taught your dog stand tall/sit up but not have taught it to perform back to back with you, I've assumed that most participants will have already trained these tricks. Please post a message to this thread to let us all know if you are going to be joining in. If you can please submit a video to this thread on or before the 17th March... the video should include: 1. Your dog doing stand tall/beg before you try to train it behind you, so we can see how confident all our dogs are with the ground work. 2. Part of your first training session showing how you set about training. 3. The final trick repeated 3 times in the same clip - you might want to think about how you would transition to and from this trick in a freestyle routine and show that in this clip too :-) If you know you won't be able to submit a video for whatever reason do please still train along with us... the more of us join in the more fun it is and the more we can learn from each other and our dogs. Any questions/suggestions/ideas/hints about this challenge please post them in this thread, ideas for other challenges please post them in "Who Is Interested In A Trick Challenge".
