I am sorry you had such a disappointing day at the festival. That lady was far more than rude. We took Roxy to her first out-with-strangers (Art In The Park) this summer and it was the total opposit of your day. Everyone stopped to talk to us and made the kindest, sweetest comments. And, everyone who wanted to pet her, asked first, even the kids. Roxy ate that up.
She got to meet alot of other dogs, too, including 2 beautiful giant sheepdogs. I didn't hear one rude "rat" comment at all. And the most personal question was "Did you get her locally?" Since she came from Myrtle Beach, no one pressed for any more info except about Yorkies in general. It was really a great experience. I hope your next festival goes much better. People can be such idiots!
