So I have been invited to do a dog trick demo for an organization that does a yearly event/ fundraiser. They do a run in the morning and I was asked to do a little demo showing how dogs can stretch before the big race and someone else will be doing a warm up with the runners. So I am trying to come up with different stretches and tricks that are stretching related. For example...bow, lifting legs...etc. So my question is do you have any good dog exercise/ stretches resources...websites/ youtube videos etc. that would be helpful for this project? What types of tricks can you come up with that could be exercising, stretching, warming up?
