I get those questions from people outside my family, too. I always say "enough to bring him/her home with me".
What bugs me is that when people see Lucy and Rebel together, they accept that Reb is a yorkie but always ask if Lucy if full-blooded because she's bigger. She's 1 & 1/2 and weighs 11 lbs. She's a little chunky and her vet says she needs to lose 2 lbs. We've been walking lots more and playing in the yard more, but it hurts my feelings when people make a big deal out of Rebel and basically ignore Lucy. She's soooo loving and smart, I think she knows what they're saying!
