⚠️

Mustard seeds contain glucosinolates and isothiocyanates which in small amounts have antimicrobial properties but in significant amounts irritate the digestive tract, cause vomiting and diarrhoea, and can affect thyroid function with regular large exposure. A few mustard seeds in a tadka that contaminated food are unlikely to cause serious harm. Deliberately feeding mustard seeds or mustard paste to dogs is not safe.

What You Need to Know About Mustard Seeds for Dogs

Rai (mustard seeds) are a fundamental tempering spice in South Indian and Bengali cooking — virtually every sabzi, sambar and dal starts with mustard seeds in hot oil. This tadka is always unsafe for dogs regardless of how many mustard seeds it contains due to the onion, garlic and other ingredients.

Mustard seeds are used year-round in tadka. Always prepare dog food separately before any spiced tempering is added.

Frequently Asked Questions About Mustard Seeds for Dogs

The mustard seeds themselves in a small amount are less concerning than the onion and garlic typically present in tadka. Monitor for vomiting and contact your vet if concerned about the amount eaten.

Is mustard sauce (the condiment) safe?

💬 Dr. Sharma's Advice

"Always focus on preparation — how a food is cooked matters as much as what the food is. Plain, unseasoned food is the rule for dogs in Indian kitchens. When in doubt, do not share."
