Can dogs eat raw bread dough?
Toxic. No, and it is two emergencies at once: the dough expands in the stomach, and the yeast ferments into alcohol.
How much is dangerous?
Merck gives no dose threshold. Dogs are the species most commonly affected, and susceptibility varies between individuals.
Why it does harm
Merck describes both hazards. Mechanically, the dough rises in the warm stomach and causes gastric distension, compromising blood supply to the stomach wall much as gastric dilatation and volvulus does, and interfering with breathing. Biochemically, yeast fermentation produces ethanol, which is absorbed and causes intoxication and metabolic acidosis.
What to look for
- Unproductive retching — trying to vomit and bringing nothing up
- A swollen, distended abdomen
- Lethargy, then unsteadiness and confusion as the alcohol takes hold
- In severe cases weakness, inability to stand, low blood sugar, low body temperature, coma or seizures
What to do
- Go to a vet now and call ahead. Unproductive retching with a swollen abdomen is an emergency in its own right.
- Do not try to make the dog vomit. A mass of dough is not something to bring back up unsupervised.
- Cooked bread is a different matter — it is the raw, rising dough that does this.
