Thank you for the info yorkielover201.....As for the people who feel the need to be rude, how about just saying "thanks for the refresher". We could all use that once in a while, and not everyone has Yorkies for Dummies.
I'm starting to have second thoughts about this forum. I deal with enough rude people (i.e. inmates) at work....it's unfortunate to see it here.
Yorkielover201, thanks for taking the time to post the info--there will be other people, like HeatherW, who will be grateful for it.
