Can Dogs Eat Radishes? (See What The Vet Says!)

can dogs eat radishes?

Dogs are curious creatures, and they also love to do the same things that their humans are doing. This includes eating what their humans eat. What dog owner hasn’t looked into the sad, imploring eyes of their canine friend while they were eating?

As a veterinarian, I am frequently asked about what human food items a dog can or cannot eat. Pet parents love their pups and want to share parts of their meals with them! But it is imperative to ensure that what you are sharing is safe.

Radishes are a crunchy, tangy, and delicious addition to salads and many other dishes. But can dogs eat radishes?

It is always important to verify that any food you are considering giving to your dog is safe and non-toxic. A number of foods that are healthy and safe for humans are dangerous for your dog.

Dogs can eat radishes. Radishes are not toxic to dogs, and many dogs really enjoy this root vegetable as a treat. However, there are some things a dog owner should consider before adding radishes to their dog’s diet.

 A Bit About Radishes

Radishes are classified as a root vegetable and grow deep in the ground as a root to the radish plant. Producers pull the plants from the ground to harvest the radish root.

The robust red colored radishes are the most popular variety in the United States. These root vegetables are commonly about the size of a ping pong ball, round, with a bright red outside. However, radishes come in a myriad of shapes, sizes, and colors.

There are varieties of tangy and almost spicy radishes, whereas others have a much lighter and sweeter taste. Some radishes are peppery, while others have a slight umami flavor.

The Nutrition Profile Of A Radish

Radishes are healthy root vegetables and have documented health benefits when included in the diets of humans. The root vegetable is high in vitamins, minerals, and antioxidants and low in calories.


The most plentiful vitamin contained in radishes is Vitamin C. This vitamin aids in immune system function to keep the body healthy and free of foreign invaders.

A 100 gram serving of raw radishes provides 18% of an adult human’s recommended daily allowance of Vitamin C.


Radishes contain minerals that are necessary for both human and animal diets. The most plentiful two minerals found in radishes are calcium and potassium.


Radishes are rich in antioxidants which are beneficial for human and animal health. In the body, antioxidants function as molecules that fight free radicals.

Free radicals are substances that can cause harm to the body if the level becomes high. They have been linked to multiple illnesses, including diabetes mellitus, heart disease, and cancer.


Radishes are high in fiber which can aid the digestion of those consuming the vegetable.

Blood Sugar Regulation

Radishes contain the chemicals isothiocyanate and glucosinolate, which studies have shown may aid in regulating blood glucose levels in the body.

Feeding Radishes To Dogs

Whether or not a dog will enjoy the taste of radishes is really a matter of individual preference and will vary from dog to dog. Dogs are omnivores, which means that their natural diet will consist of meat and plant material.

Some dogs love radishes and will consume them as a crunchy treat. Other dogs may be put off by the strong flavor of some radishes. There are also dogs who may not love radishes but will eat them because their owner is offering them, and they perceive the radish as a special treat of their human’s food.

Dangers Of Feeding Radishes To Dogs

Though radishes are a healthy snack for a dog, there are some things to be aware of before you feed them to your dog.

Gastrointestinal Issues

As mentioned before, radishes are high in fiber. This can be healthy and aid their digestive tracts; however, fiber can cause issues too.

Some dogs, like their human counterparts, are sensitive to fiber. Ingesting too much fiber can lead to gastrointestinal issues such as gas and loose stools.

The number of radishes that may cause intestinal upset varies widely between dogs. Some may be able to eat a lot of raw radishes and never have any type of issue. However, some dogs may become ill from consuming a single radish.

It is essential to start with a very small amount anytime you are introducing a new food into your dog’s diet.

On the other hand, for a dog that is already having loose stool or diarrhea, adding fiber to the diet can actually improve their stool. Though radishes are not usually the fiber supplement recommended for this, they could work, in theory.

Allergies To Radishes

A human or dog may be allergic to any food, and radishes are no exception. Though there are no documented cases of dogs being allergic to radishes, it is always possible.

Signs that may be seen if a dog is allergic to radishes include:

  • Vomiting
  • Severe diarrhea
  • Hives or itching
  • Facial Swelling
  • Lethargy

If any of these are seen after a dog eats a radish, you should immediately take your pet to the nearest emergency veterinarian or an emergency hospital.

How Many Radishes Are Safe To Feed A Dog?

As mentioned earlier, this is very dog specific. In most cases, if radishes are given in small amounts, the majority of dogs will not experience any ill effects.

Keep in mind that moderation is an important factor. Always introduce new foods or treats slowly and in small amounts. You can get an idea of whether or not the dog is going to tolerate the addition.

Always contact your veterinarian if you have any specific questions about your dog’s dietary needs or whether you should feed a particular food or treat.

Types Of Radishes Dogs Can Eat

Many pet parents wonder if the way the radish is prepared makes a difference in the safety of feeding radishes to their dogs.

Raw Radishes

For dogs, raw radishes are the most commonly fed type of radish. Most dogs will do fine if fed small amounts of raw radishes.

It is important to ensure that the radish you are feeding to your dog is fresh and is not rotten or moldy. Though rare, molds that grow on vegetables can have severe side effects for dogs.

Raw radishes tend to have a stronger flavor than their cooked counterparts. Many dogs do not enjoy the taste of raw radishes, and if this is the case with your dog, you may want to try a different treat.

Cooked Radishes

Cooked radishes may be more palatable to our furry friends as the cooking process gives the vegetable a milder flavor.

A cooked radish alone is safe to feed your dog. However, it is essential to be aware of any seasonings on the cooked radish that are toxic.

Ingredients to watch out for include:

  • onions
  • garlic
  • salt
  • fatty oils or butter

Onions, garlic, and salt are all potentially toxic to dogs, especially in large quantities. Fatty oils and butter are not toxic but can definitely cause a dog gastrointestinal distress.

What To Do If Your Dog Eats Radishes

In some cases, a dog will get into something they should not and will eat radishes that were not given to them as a treat. This can be a different situation than a dog who is being intentionally fed a radish.

If your dog has gotten into the trash or has eaten radishes without your knowledge, it is unlikely that a small amount of radish will be a problem for them.

Suppose your dog consumed a large amount of radishes, or the radishes were coated with toxic substances, or even contained in a dish that could have other toxic ingredients. In that case, you should contact your dog’s veterinarian right away.

Ingesting human food or getting into the trash puts dogs at a high risk for pancreatitis, which can be fatal. The owner should catalog what was in the trash or food the dog ate and take the list to the veterinarian with the dog.
