FAQs

When we share our food with dogs, we need to be extra careful because their digestive systems work differently. Lots of human foods can upset their stomachs or cause other problems.

Take supermarket mustard, for example—it often has extra stuff like vinegar, salt, and spices that aren’t great for dogs. If you’re having hot dogs with mustard and your dog sneaks a bite, they might accidentally get too much mustard (and hot dogs are also not ideal for dogs). So, it’s a good idea to keep mustard and other similar condiments away from them to avoid any issues.

Why is mustard bad for dogs?

Mustard is bad for dogs mainly because of the ingredients that can irritate dog’s stomach and the mustard seeds, which are toxic to dogs. These seeds contain glucosinolates, which turn into isothiocyanates—compounds that can upset your dog’s stomach, leading to issues like stomach pain, diarrhea, and vomiting.

While a small amount of mustard might cause mild discomfort, your dog won’t experience mustard seed toxicity if they eat mustard! It has to be a significant amount of pure mustard seeds, and even then, toxicity may not occur.

Another useful thing to know is that mustard also has goitrogens, which can interfere with thyroid function, but this typically requires a large amount. So, while a tiny bit might not be a disaster, it’s best to keep mustard out of your dog’s reach to avoid any potential issues.

Common sense when it comes to mustard

While mustard seeds are toxic to dogs, mustard itself won’t harm your dog instantly. This information helps you avoid it, but it doesn’t mean that mustard will cause lasting harm. So, if your dog eats a little, don’t panic—just keep mustard away from them in the future.

Different types of mustard, ingredients, and why they’re not safe for dogs

Along with the toxic mustard seeds, mustard contains other ingredients that can irritate your dog’s stomach.

Vinegar: The acidity in vinegar can upset your dog’s stomach and lead to gastrointestinal discomfort.

Salt: Our condiments often contain too much salt, which dogs can’t handle well. Eating foods with lots of salt can cause dehydration and upset their stomachs.

Spices and seasonings: Ingredients like garlic, onion powder, or mustard powder can be harmful, as they irritate a dog’s stomach and can cause digestive issues.

Sugar: Excess sugar can contribute to obesity and dental issues in dogs.

What to do if your dog eats too much mustard?

Thankfully, mustard isn’t toxic to dogs. If your dog happens to eat too much mustard, you might see some gastrointestinal upset like lack of appetite, vomiting, or diarrhea. These symptoms are usually short-lived and should resolve on their own without needing any special treatment.

There’s no need to induce vomiting or seek treatment unless the symptoms are severe or persistent. Just keep an eye on your dog and make sure they stay hydrated.

However, if your dog eats a whole jar of mustard, it might be a good idea to offer them more food to help dilute the mustard they ingested. You can give them plain foods like pumpkin puree, lactose-free milk, or chicken broth. These can help soothe their stomach and flush out the mustard. Just be sure to monitor them for any signs of discomfort and keep them hydrated. If you’re worried or if their symptoms don’t improve, it’s always best to consult your vet.

Love, life, and fur forever!
