Did you know?

Sourdough bread is one of the oldest forms of leavened bread — evidence of sourdough bread dating back 6000 years has been found in archaeological sites in Europe and the Middle East. The San Francisco sourdough tradition dates to the California Gold Rush of 1849 when bakers carried starter cultures in their kits. A sourdough starter is a living culture that can be maintained indefinitely — some bakeries claim to use starters over 100 years old.

What You Need to Know

Plain baked sourdough bread is not toxic to dogs in small amounts but has no nutritional value for them. The critical safety issue is raw sourdough dough — the active sourdough culture continues fermenting in the warm stomach environment producing CO2 (causing dangerous bloating) and alcohol (causing toxicity). Only fully baked sourdough is safe. Many artisan sourdoughs contain significant salt. Sourdough with additions like garlic herbs or olives should be avoided completely.
