2. Bread dough (yeast)
Raw bread dough (and the yeast inside it) is doubly bad for cats and dogs: The unbaked bread dough can expand in the stomach, while the yeast produces alcohol. The rising dough can bloat or twist the pet’s stomach, potentially causing vomiting, retching, weakness, an abnormal heart rate, collapse, and death.
The yeast, on the other hand, can give your pet alcohol poisoning and subsequent drops in blood sugar, blood pressure, and body temperature. If your pet is really intoxicated, they can suffer seizures and respiratory failure. While you might like to eat bits of cookie dough, don’t let your pet eat dough.
