Is Mustard Toxic For Dogs?

Mustard seeds are the main ingredient in mustard. Eating mustard seeds can lead to inflammation of the stomach or intestinal tract, known as gastroenteritis. The toxic component of mustard resides in the mustard seeds, which contain glucosinolates.

Therefore, the consumption of large amounts of this ingredient can induce adverse effects in your dog. If your dog eats a hotdog or hamburger with mustard on it, it might not have any symptoms. 

However, if you notice that he ate a large amount of mustard and is lethargic because of this, then be sure to call the vet right away.

Symptoms to be aware of:

  • Abdominal Pain
  • Diarrhea
  • Drooling
  • Gastroenteritis (inflammation of the stomach and intestines)
  • Vomiting

Is it safe for your dog to eat mustard greens?

However, it is only the mustard seeds that are toxic for your dog. Mustard greens are a different story.

Mustard greens and other cruciferous vegetables like cabbage and broccoli can offer plenty of health benefits for your dog. Mustard greens contain a variety of nutrients, like potassium, phosphorus, and fiber. 

Mustard greens, along with other cruciferous vegetables, should always be cooked before serving up for your dog. Never feed them raw. Your dog will not digest the mustard greens, and they may cause some gastrointestinal upset.

However, when cooked, the heat softens the greens, and they are much safer for your dog to eat, not to mention more straightforward for them to digest.

Should you boil or steam mustard greens

If you would like to add mustard greens to your dog's diet, you should steam them so that they retain their nutrients. Boiled vegetables lose all their nutrients in the water.

They then evaporate, meaning that there is no nutritional value in the cooked veggies and no point in feeding them to your dog apart from the fiber content. 

Steaming or blanching are your best options for preparing mustard greens and other safe greens and vegetables that you would like to feed to your dog.

 Do not feed these foods raw, though, because if you do, it may lead to the suppression of your dog's thyroid function further on down the line. When boiled, steamed, or blanched, the fiber is soft and mashable. 

The nutrients, vitamins, and antioxidants and digest the food more effectively. Pureeing vegetables is an excellent idea to make them more digestible for your dog.

What Will Happen If My Dog Eats Mustard?

Your dog may experience severe gastrointestinal upset. Your dog is more than likely to vomit and have diarrhea and discomfort due to gas and various forms of inflammation.

The more mustard or mustard seeds your dog has ingested, the worse their symptoms are likely to be. 

Mustard condiments contain many mustard seeds, so your dog will not have to eat very much of them to experience the adverse effects. Small dogs are especially at risk due to their small size and smaller digestive tracts. 

Therefore, a lesser amount of mustard can have a significant impact on a smaller dog. If you are concerned because your dog has eaten mustard, you should watch out for the main symptoms of stomach upset, including vomiting and diarrhea.

The signs of vomiting are:

  • Drooling
  • Licking the lips
  • Pacing
  • Lethargic

Signs your dog may experience diarrhea

If your dog is about to experience diarrhea, it may suddenly become restless or seem panicky and look for a way to get outside to release its bowels.

If your dog is feeling sick, they might stop responding to you or anyone else in the house. If this happens, it may be because of their low energy levels and discomfort. 

They could also hide somewhere and not eat any food or show interest in playing with toys either. If you press gently on your dog's abdomen, your dog may also experience discomfort or pain. It would be best to be careful when doing this because some dogs may unintentionally lash out due to the pain, and you could get bitten. 

If your dog is exhibiting any of the following symptoms, you should call a veterinarian for advice. They may ask that you bring them in to examine the animal and run tests on it as needed. 

Don't hesitate to call your vet, especially if your dog has been vomiting, as this can lead to dehydration and electrolyte inequalities, which in some cases can be fatal for your dog. The sooner your dog gets treatment, the better.

How Will The Vet Treat A Dog That Has Consumed Mustard?

If your dog has consumed a toxic amount of mustard, the first thing your vet will want to do is try to induce vomiting. Especially the case if your dog consumed the mustard just a short time before you brought them in to see the vet.

Induce Vomiting

Induced vomiting removes most of the toxic food from the dog's stomach so that the body cannot absorb as much of the toxic compounds.

One of the main reasons it is essential to bring your dog in to see a vet as soon as possible is because the sooner this procedure takes place, the better chance your dog will have to avoid severe complications.

Activated Charcoal

Activated charcoal can be used to absorb any residual toxins in your dog's system. First, the vet will give an injection, which causes the activated charcoal to immediately absorbs every toxin left behind and makes it easier for your pet to throw up everything out of its stomach.

Can Dogs Eat Honey Mustard?

You may wonder if honey mustard is safe for your dog to eat, as this is an ingredient commonly used to dress salads and marinate meats that your dog may also have the pleasure of sampling.

You may also be curious because honey is known to have multiple health benefits for both humans and dogs, helping to reduce painful infections, healing wounds, and increasing energy. 

In small amounts, your dog may not have any adverse effects on your dog's health. However, the mustard will affect your dog's gastrointestinal tract.

Can Dogs Eat Other Types of Mustard

In America French's yellow mustard is the most common condiment used on hotdogs and hamburgers. If your puppy eats a hotdog or hamburger with a small amount of yellow mustard you shouldn't panic.

Summary

There are plenty of human foods that are toxic or unhealthy for dogs, and these can be highly detrimental to your dog's health, and in the worst-case scenario, the results can be life-threatening. 

There will always be those dog owners that claim that their dog has eaten all of the toxic foods under the sun, including mustard, and that no harm ever came to them.
