Hey, sorry i don't have any help for you, but I feel bad that no one has responded to this. It's a good question. I hope someone can answer it for you. It seems that if you post a serious question a lot of times you only get one or two responses (My guess is that not very many know the answer). If you post pics you get 50 (everybody knows how cute Yorkies are). I hope some one will answer this. I would like to know too.
