Hi All!
I'm so glad that I signed up to talk with you as I was worried about the same thing. I currently have a 17 lb. Cairn terrier who I love dearly, and who sadly has lung cancer. I had often thought about a Yorkie, but am really scared to go down in size. I originally had Great Danes... so my Cairn was a HUGE step down physically... he thinks he's Great Dane size! The bell is a wonderful idea, even if I decide to stay Cairn sized! I never thought of it, but you only trip over them when they sneak up on you and you don't know they're there.
