What You Need to Know

Miso paste is a fermented soybean product with very high sodium content. A single teaspoon of miso paste contains as much sodium as some dogs should consume in a day. Traditional miso soup also contains dashi stock — made from kombu seaweed high in iodine — and is garnished with green onions which are toxic. The tofu component is safe. None of this matters because the sodium and green onion content makes miso soup unsafe for dogs overall.
