I've got to say, I must live a very sheltered life. If some whom I had actually asked to come over (ie pizza guy) asked me to put Meg away, I would close her in separate room in a heartbeat. Granted, I'm pretty sure someone could torture me to death, slowly, and she would be trying to sit in his lap and get cuddles, so it's not like she'd do me much good in any situation.
I'm amazed at the number of discussions that come up here about dogs protecting people/wanting to get a dog for protection/will a dog actually protect, etc. I've never considered myself an optimist, but this is either a very paranoid group of people, or you must live in some scary towns! I mean, I know "it" can happen anywhere - we had a murder on our street last year. But I'm pretty sure I meet a lot more people who are scared of dogs genuinely than people who want to harm me.
I'm not judging people who feel the need for the protection, just surprised.
