Oh Kirsten, I'm so sorry to hear this. Has she been drinking? Could it be that she ate something poisonous during the day? I know you have a list of poisonous plants, but I also know you are careful.

Any Emergency vet you could call and ask what to do? A tranquilizer like 5 mg of Valium would probably do your both good.

More good thoughts coming from Fister and me.
