Many foods are potentially toxic to dogs. One that is extremely dangerous is bread dough.  The mixture contains yeast as a leveling agent and therefore can expand many times its original size. This is exactly what happens when your dog swallows bread dough. As the dough swells in your dogs stomach it starts to ferment producing alcohol which is toxic to your dog. Even ingesting small amounts of bread dough can cause your dog pain, bloating and vomiting.  It can also leave him feeling disoriented and listless. Pet medication will not help him feel better.  If he’s eaten a lot, he may end up in the operating room requiring surgery to remove the mass.  Your dog will also need treatment for alcohol poisoning. If you a bread maker, make sure to keep your dog out of the kitchen while you’re baking!
