Our mini poodle had just one a few years ago while staying with my DD. Scared her but she just sat on the floor with him and kept petting him. She called the vet and she told her that poodles are prone to them and to keep little packets of honey handy and if it happens again put just a little on his tongue and it helps ease them. He's never had another one so don't know if it really works or not. It is hard when something like this happens. They're our kids and there's nothing we can do to help or make it go away.
