Just curious what everyone here uses/has used/has seen being used and the pros/cons of the many ways people use to ID their puppies. A lot of folks in my breed use nail polish, actually haven't seen many who use anything else. Just something I have been thinking about lately For those who are knowledgeable with ric rac, does it fray too much (the #1 issue I have heard with it)? Is ribbon a BIG no no (it seems those who use it like it, and those who don't say it's the one thing never to use)? Is there a difference between breed sizes when making a consideration (besides thinner pieces)?
