Well, I don't blame you - I wouldn't be over it either. Wow! What an awful experience. Nothing like a Yorkie screaming in your ear to get your attention huh?!
I might have given thought to a muzzle (YK) right about then! OMGoodness what a little stinker.
I wonder what in the world gets into them to make them behave that way? Tink doesn't like car rides, but she just stands the whole time with her head down facing me. It's sad, but at least she's not screaming.
I sure hope your baby calms down soon. I'm afraid I can't offer any advice.
