Ok, I'm sure y'all are tired of me bugging you about showing, but, here I go again. I've been told to use a dog pinch chain for my wether for showing, so I went and got on today and it looks huge on him! It's 3.0 mm x 18". It fits him length wise, but the links look huge! And the only smaller size they. Had were like chihuahua chain. Tiny! So, what size chain do y'all use?
