Can dogs eat soy sauce?

No — salt overload

No. Soy sauce is extremely salty — just a tablespoon can cause salt poisoning in a small dog.

The full picture

Soy sauce is one of the saltiest common kitchen ingredients — around 900 mg of sodium per tablespoon. A single tablespoon can cause symptoms of salt toxicity in a small dog, and larger amounts can be genuinely dangerous. Asian takeaways often contain enough soy sauce to cause issues. A few drops licked from a plate probably isn't an emergency, but make fresh water available and monitor. Low-sodium soy sauce is still salty enough to be problematic. Tamari, oyster sauce, teriyaki sauce, and fish sauce all have the same warning.
