Can Dogs Eat Mustard?
No — mustard seeds contain toxic compounds and the condiment has vinegar and spices that irritate the digestive tract.
Mustard is not safe for dogs
Mustard seeds contain isothiocyanates and glucosinolates that cause GI inflammation. The condiment also contains vinegar, salt, and spices. A small lick of yellow mustard is unlikely to be an emergency, but should be avoided.
