ASPCA Animal Poison Control — People Foods to Avoid Feeding Your Pets · reviewed 2026-08-07 · confidence: high
Why
Extremely high in salt — a tablespoon can carry more sodium than a small dog should have in a day. The ASPCA lists excessive salt as causing thirst, vomiting, tremors and seizures at high intake, and many soy-based sauces also contain garlic.
Signs to watch for if your dog has eaten soy sauce
Drinking and urinating far more than usual
Vomiting and diarrhea
Wobbliness or weakness
Tremors or seizures at high intake
Signs vary with the amount and with the individual pet, and some appear only after a day or more. Their absence does not mean your dog is in the clear — call rather than watch.
What to do now
Don't feed it. If your dog has already eaten some, call your vet or poison control with the amount and the timing and follow their advice.
Never induce vomiting and never give any medicine unless a vet tells you to. With some substances it causes more damage than the poison. This page tells you when to get help — it never tells you how to treat at home.
Safer alternatives for dogs
Plain baby carrots or carrot sticks
Plain cooked chicken breast — no skin, no bones, no seasoning
A few blueberries or a slice of apple with the core removed
