Soy sauce is safe for dogs
While soy sauce is not toxic, it should not be fed to dogs. Soy sauce has a very high salt content and can be dangerous to dogs. The high sodium content of soy sauce can cause dehydration and electrolyte abnormalities. Ensure that your dog has access to lots of water if they have ingested soy sauce and contact a veterinarian if they show signs and symptoms of dehydration.
