Duct tape?
I remember one event that ended up being filmed, and I think it was Scent hurdle, and the comment was made.... ladies, please, buy better bras!
We did use duct tape at one flyball weekend, one team member had a shoulder injury so it took three of us to tape the shoulder so it didn't dislocate, one had a bum knee and had to have it wrapped and my darling dog missed the toy on the runback and chomped my hand rather well, didn't need to be bandaged but it was easier to have it wrapped than it was to shake hands all day in pain.
