Can anyone tell me what leads collars and muzzles are allowed and are not in greyhound racing in nsw. In the english and irish races i've seen the some greyhounds are lead to the box's with slip type collars and leads, in the american races i've seen they wear a plastic type muzzle. I Am only new to greyhound racing and had nothing to do with it before and only have raced my dog once and have only standard race equipment for him, i know this is all i need. But for knowledge sake can anyone help.
