Not a lot you can do other than give her some additional foods to try to dilute it. It will not hurt her if it was just a little. Most animals do not like coffee. Matter of fact, I have used coffee grounds to keep animals (mainly dogs) out of my garbage. Are you sure she did not get into something else? I don't mean to doubt you but you may want to make sure. A little coffee should not make a dog run like this.
Do what I do. Give the vet an emergency call. Someone picks up. Explain the situation. Then they'll tell you what is going on and how to solve it. I did that today. Don't hesitate to call the emergency #, even if it isn't an emergency. Half the time I call it's nothing, so you can't seem as helpless as me when it comes to the dog's problems=)
