Soy sauce is a fermented seasoning made from soybeans, salt, water, and usually wheat, then aged for deep savory flavor. It is used in marinades, stir-fries, noodle bowls, sushi dipping, and glaze sauces. The finished liquid is highly concentrated in sodium.
Common styles include light soy, dark soy, tamari, sweet soy, and low- sodium versions. Even reduced-sodium products remain salty for pets. Prepared sauces such as teriyaki or stir-fry blends often add garlic, onion, sugar, chili paste, or vinegar.
Traditional brewing ferments soybean mash for months, while some products use hydrolyzed vegetable protein and added color. Takeout packets from sushi, ramen, and rice bowls are frequently left in delivery bags or on counters. Pets can puncture those packets easily and create concentrated spills in a small area.
Pet exposure usually comes from takeout packets, dipping bowls, and pan sauces left on plates. A few licks may deliver a large sodium load because the seasoning is concentrated. For pets, avoid soy sauce and keep soy-glazed leftovers and condiment cups out of reach.
