LOL!!
I let people touch my girls but not just ANYONE.. I don't drag them out unless they've had they're shots so I won't have to worry about them getting sick from people touching them.. You can tell by looking at people if they mean well or if they come from less than sanitary conditions...
We were just at the petstore yesterday and there was another person in there who owns and breeds yorkies.. I definitely don't mind them petting or holding my babies..
