Hi Guest
It depends on what breed you have and how they are shown. What is correct for a setter would be incorrect for a terrier.
Could you ask your dogs breeder or go along to a show and see what type is being used for your breed.
Failing that, try typing your breed into Google and visit some websites of the breed, there may be photos of a dog in a show stand with lead on.
Sorry, can't be of more help without the breed.
