SnoutScanIs mustard seed safe for dogs?
No. Mustard seed is toxic to dogs.
Irritates the stomach and gut and can cause vomiting and diarrhea. The harm depends on the amount, so a trace is less risky than a spoonful, but it adds no nutritional value.

Common questions
Are mustard greens the same thing?
No. Mustard greens are the leaves, and a little cooked is fine for most dogs. The seeds and the powder made from them are what upset the gut.
