Raw yeast dough is unsafe at any amount. When swallowed, it expands in the stomach and produces ethanol from fermentation — a potentially fatal emergency. Contact a veterinarian immediately if ingestion occurs.
Raw bread dough is unbaked yeast dough that continues fermenting and expanding while proofing. Often left in bowls, pans, or trays on warm counters during prep.
Pizza and sweet roll dough create the same expansion and fermentation risk. Rising bowls should be kept behind closed doors when pets are present.
Refrigerated doughs and thawing frozen dough can be just as hazardous once fermentation resumes. Canned biscuit and roll dough should also be treated as unsafe.
