Sorry that you had a bad experience with some of the responses you got. Unfortunately, that is the downside of posting on a public forum full of people so passionate about this breed--when you post about something, essentially you have made it 'everyone's business' in a sense that you've opened it up for converstation and occasionally scrutiny. You will get a wide range of answers, some you will like, some you will not. You have to take the good with the bad--you can not pick and choose who responds and what kind of comments you get and you have no control over who can and cannot respond. Just one of the aspects you have to learn to deal with and accept.
Hopefully you will find the perfect home for this little one where it can be loved and cared for by someone experienced enough to provide the special kind of care required for a smaller Yorkie. Good Luck!
