Why?
Raw bread or pizza dough containing yeast is dangerous for two reasons: the dough expands in the warm, moist environment of the stomach potentially causing bloat, and the yeast produces ethanol as a byproduct causing alcohol poisoning.
How much can dogs have?
NONE. Uncooked yeast dough of any kind.
What to watch out for
Symptoms include distended abdomen, vomiting, weakness, and signs of alcohol intoxication. Bloat from expansion can be fatal without emergency surgery.
🚨 If your dog ate raw dough: Contact your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 right away. Don't wait for symptoms — many toxins act internally before signs appear.
