What makes it harmful
mustard seeds contain irritating compounds; prepared mustard can also contain salt, vinegar, garlic, onion, or sweeteners
What to do if eaten
If more than a lick was eaten, or the product contains onion, garlic, xylitol, or another unsafe ingredient, contact a vet or poison-control service.
How to serve safely
Do not add mustard to dog food. A tiny accidental lick of a plain condiment is usually a watch-and-call-your-vet situation rather than a reason to induce vomiting, but larger amounts or seasoned products need veterinary advice.
