if you are trying to stop stoppers from getting damaged get yourself a bike inertube and a piece of hollow tube that will fit over your dogs foot , stretch the inertube over the tube, slip tube over dogs foot, pull a bit off the inertube onto th dogs leg/wrist hold and then pull the tube of leaving the inertube over your dogs stopper, will not hinder your dogs movement, TIP if you struggle to get the inertube off the tube put some talcum powder on the tube before you put the inertube on
