What You Need to Know

Active baking yeast — whether dry or fresh — remains biologically active when consumed by a dog. The warm environment of the stomach provides ideal fermentation conditions. Yeast rapidly ferments sugars producing ethanol and CO2 gas. The ethanol causes alcohol toxicity and the CO2 causes significant gastric distension that can progress to bloat. Raw bread dough carries the same risk. This is a veterinary emergency requiring immediate treatment.
