What You Need to Know
Baked sourdough bread is not acutely toxic in tiny amounts — the baking process kills the active yeast and drives off the alcohol produced during fermentation. However raw sourdough starter and unbaked sourdough dough are toxic because the active yeast continues fermenting sugars in the dog's warm stomach producing ethanol. Commercial sourdough is also high in sodium. A small piece of fully baked plain sourdough is unlikely to cause serious harm but should not be given intentionally.
