Don't feed your dog bread dough. When bread dough is ingested, it rises in a dog's stomach and as the dough ferments, alcohol is produced. After ingestion, dogs will act nauseated, vomit, act painful, lethargic or become disoriented.
The problem with bread dough ingestion can be from the severe distention of the abdomen as the dough rises in the stomach or from the alcohol produced as the dough ferments causing alcohol toxicity.
If your dog accidentally ate some dough, call your veterinarian or local emergency clinic.
