We had a get together here in the Phoenix area and Joey was around 8 other yorkies and a cat. He started drooling, and after awhile it looked like foam was on his chin. He'd been around other dogs before and never acted like this, I'm guessing maybe it was the cat, but he hasn't done since. He's not the social butterfly I was expecting. Hopefully, Javah is just teething and not the nervous type.
