Red: toxic
No, raw yeast dough is dangerous for dogs. The dough expands in the stomach, while the yeast produces alcohol. Both can be life-threatening.
Why yeast dough is dangerous
According to the MSD Veterinary Manual, the warm, moist stomach acts like an incubator for yeast. The dough rises, the stomach swells, blood flow to the stomach wall decreases and breathing becomes difficult. In some dogs, the stomach can even twist. At the same time, alcohol is produced and quickly enters the bloodstream. The Pet Poison Helpline explains that blood sugar, blood pressure and body temperature can then fall dangerously low. According to MSD, dogs are affected most often because they eat whatever they find.
What are the signs?
The Pet Poison Helpline lists vomiting, unsuccessful retching, a swollen abdomen, lethargy, staggering, weakness and, in the worst cases, coma. According to MSD, hypothermia and seizures can also develop later.
What to watch for
- Keep dough well out of reach: Never leave yeast dough to rise on a table, chair or radiator within your dog’s reach.
- Pizza and bread roll dough count too: Any raw dough containing yeast is a risk, including scraps left in the bowl.
- Baking days: There is often plenty of baking over the holidays. Be especially careful to keep your dog out of the kitchen.
What if your dog has eaten yeast dough?
Call your vet or an emergency veterinary service immediately, even if your dog still seems normal. Be ready to explain what kind of dough it was, roughly how much was eaten, when it happened and how much your dog weighs. Do not give home remedies or induce vomiting yourself. Your vet will decide what treatment is needed.
If you suspect poisoning, take your dog to a vet or an emergency veterinary service immediately.
