The primary danger of raw bread dough for pets is yeast fermentation in the stomach. When pets ingest raw bread dough, the warm environment of their stomach causes the yeast to ferment and produce gas. This gas can lead to bloating and potentially dangerous levels of expansion of the stomach, which can lead to gastrointestinal issues, discomfort, pain, and potentially life-threatening conditions such as gastric torsion (gastric dilatation-volvulus syndrome). Additionally, the expanding dough can cause mechanical obstruction in the digestive tract.
