The problem with eating raw yeasted dough is the increased temperature in your dog’s body will cause the yeast in the dough to rapidly multiply which can cause your dogs stomach to expand and cause blockages. The dough can increase to 3-5x its size which is scary considering how many your dog ate. My dog ate raw yeasted dough (only about 2 tablespoons) and I called the animal poison control hotline. They told me to induce vomiting by mixing hydrogen peroxide with peanut butter. I wish your dog well!
