Mustard is a condiment made from the seeds of the mustard plant. It comes in different types, including white, brown, and black mustard seeds. Mustard adds a sweet or tart flavor to meals and is normally used in various cuisines around the world.

But, when it comes to dogs, it’s important to exercise caution with mustard. Mustard seeds and the condiment itself are considered unhealthy for canines.
Reasons to Not give mustard to dog
Here are some reasons to avoid giving mustard to your dog:
- Added Ingredients: Mustard condiments often contain ingredients like garlic, turmeric, and paprika, which can be problematic for dogs. These ingredients can cause digestive issues and discomfort for dogs, leading to symptoms such as vomiting, diarrhea, restlessness, stomachache, and decreased appetite.
- High Sugar and Salt Content: Condiments, including mustard, often have added sugar and salt. These ingredients can increase thirst in dogs, leading to sodium ion poisoning and various discomforting symptoms such as vomiting, diarrhea, depression, lethargy, excessive thirst or urination, physical incoordination, and high temperature.
- Mustard Seed Toxicity: Mustard seeds contain toxic compounds such as isothiocyanate and glucosinolates. These compounds can irritate the mucous membrane in a dog’s stomach, causing ulcers. Dogs may experience upset stomach, vomiting, diarrhea, and allergic reactions if they consume mustard seeds.
It’s also important to avoid giving other forms of mustard to your dog:
- Wild Mustard: Wild mustard, also known as field mustard, contains compounds like isothiocyanate and goitrogens, which can irritate a dog’s stomach and cause stomachaches, ulcers, and disruptions in thyroid gland function.
- Whole Grain Mustard: Whole grain mustard varieties, such as dijon, French, and Chinese hot mustard, contain visible seeds that can be harmful to dogs. Consumption of whole grain mustard, especially in large quantities, can lead to continuous diarrhea, vomiting, and other adverse effects.
- Mustard Oil: Mustard oil, while healthy for humans, can lead to orotic acid toxicity in dogs. It’s best to avoid using mustard oil on your dog’s skin as they may lick it, potentially causing health issues.
- Mustard Powder: Mustard powder is also not healthy for dogs and can cause vomiting and diarrhea. It’s important to keep mustard powder away from dogs to prevent them from sniffing or ingesting large amounts that can block their throat and cause choking.
While mustard seeds and sauce can have negative effects on dogs, mustard greens can be a healthy option in small quantities. Mustard greens are low in calories and provide essential nutrients. However, feeding too many mustard greens can cause diarrhea, stomachaches, and gut inflammation in dogs. It’s best to give your dog small amounts of mustard greens occasionally and ensure they are cooked or steamed to make them easier to digest.
In conclusion, while mustard can be enjoyed by humans, it’s generally best to avoid giving it to dogs due to potential health risks. If you have any concerns or if your dog has consumed mustard or related products and is experiencing adverse effects, it’s recommended to consult with a veterinarian for proper guidance and care.
