I did a search and I was surprised that I couldn't find any information on dangerous tricks on this forum. I just watched this video from a respected positive reinforcement trainer (this might relate to the tread posted earlier about AF vs Balanced) First, Do you agree with what she is saying, or do you think she is being over protective? I would also like to know from the people that agree, what tricks are dangerous for German Shepherds to perform? She mentions in the video that all breeds are different, and I know hips should be looked out for, but is this in all GSDs? or just ones that have OFA hips less then ideal? She also talks about the risks in agility and I know a lot of people on this forum do agility, so I would very much like some input on that as well. Thanks everyone for checking this out.
