My dog just ate French crepes!!! Help! ?

My 7 month old chocolate lab got into 2 French crepes that consist of 3 eggs, 2 cups of all purpose flour and a teaspoon of sugar. He has puked a yellowish gooey throwup 14 times in the last 30 minutes. He's fine until his he starts to shake, cry go in a corner and upchuck. He's laying down right now and not even chewing his favorite bone! Please help me! Are any of those ingredients hazardous?
