Hi Mary,
I take it from previous posts she's a Dobermann? What leads and collars are they normally shown on? - a check chain and leather lead perhaps?
A show lead would normally be thinner than a normal day lead, rolled leather ones look nice - perhaps 8mm rolled? - but obviously sufficiently thick to control and hold your dog securely.
Brass or chrome probably doesn't make much difference on a Dobe, although on pale breeds brass can turn the neck green. Brass clip if you have a brass collar, etc.
That's my two penn'orth, hopefully somebody more up on showing Dobes will be along shortly if I need putting right :D
