Can Dogs Eat Broccoli? 5 Amazing Health Benefit & Risks

Broccoli is just one of those vegetables you have a hard time getting your kids to eat. But the reality is that this vegetable has a ton of excellent vitamins and minerals. But you may be wondering if dogs can eat broccoli while enjoying the same benefits.

Yes, Dogs Can Safely Eat Broccoli

Dogs can absolutely eat broccoli, but only in moderation. However, if your dog consumes too much broccoli in a single serving, they may risk experiencing negative side effects. Most commonly, they may have an upset stomach to a certain degree.

But don’t let the potential side effects deter you from giving them a reasonable serving of broccoli. As long as you keep the feeding to a moderation, dogs may reap the amazing health benefits. And trust me, there are health benefits to eating broccoli.

5 Health Benefits For Dogs

As kids, most of us were always told to eat our broccoli. But why? It’s not like broccoli is the best tasting vegetable we can find. Maybe far from it. But the reason is because of all the great vitamins and nutrients in these veggies. Broccoli is considered by some to even be a superfood.

Before we dive into the health benefits that your dog may receive from eating broccoli, let’s examine the nutrients.

In One Cup of Broccoli (156 grams):

  • Vitamin K – 245% Daily Value
  • Vitamin C – 135% DV
  • Chromium – 53% DV
  • Folate – 42% DV
  • Fiber – 21% DV
  • Pantothenic Acid – 19% DV
  • B6 Vitamin – 18% DV
  • Vitamin E – 15% DV
  • B2 Vitamin – 15% DV
  • B2 Vitamin – 15% DV

1. Broccoli For Strong Bones in Dog

Looking at the nutritional numbers of broccoli, you may notice that Vitamin K sticks out. One cup of this vegetable can provide your dog with an unreal amount of this vitamin. But what exactly can Vitamin K do for you and your dog?

Vitamin K has been known to improve bone density in your dog, thus promoting stronger bones. This means that a little boost of this vitamin can help older dogs that need a little help in that department. But broccoli and Vitamin K isn’t just for old dogs.

A young energetic or working dog breed can benefit from stronger bones due to their active lifestyle. If you have an active dog breed, such as a Border Collie or Jack Russell Terrier, a little broccoli would likely be great for them.

Fortunately, you can find this vitamin in many dog safe human foods. But they probably won’t have as much per serving as broccoli. Other vegetables with a sizeable amount of Vitamin K include cucumbers, kale, and celery.

2. Broccoli Helps Battle Diseases in Dogs

These dark green vegetables are loaded with Vitamin C. Some people argue that dogs don’t necessarily need extra Vitamin C in their diets. Although there is some merit to the argument, it’s not completely true for all situations.

Yes, dogs naturally produce Vitamin C, unlike humans. This is why humans are recommended to get their daily dose of Vitamin C for a healthy lifestyle. However, an aging dog may not be as efficient or effective at naturally producing this vitamin.

This means that an aging dog may actually benefit from broccoli’s powerful vitamin. Older dogs are also more prone to diseases and cancers, which Vitamin C has been known to battle. Too much C in their system won’t likely hurt them because they will urinate the excess vitamin.

Other fruits with a healthy amount of Vitamin C include: oranges, strawberries, kiwi, bananas, pineapples, mangoes and blueberries.

3. Broccoli Promotes a Healthy Dog Heart

Yes, bananas are known to have a ton of Potassium. But with 13% of the human’s recommended daily value, broccoli has a pretty respectable amount of Potassium too. However the question is, how does Potassium benefit your dog?

Potassium is an electrolyte mineral that serves a purpose for a lot of bodily functions. But perhaps the most notable is its ability to promote a healthy heart in both humans and possibly dogs. In fact, low Potassium levels have been linked to irregular heartbeats (Arrhythmia).

The occasional serving of broccoli may actually be a great idea for an aging dog that may encounter Arrhythmia. But never use broccoli as a main treatment for the condition. If your dog was diagnosed with Arrhythmia, consult with your vet about feeding them broccoli.

Other amazing fruits and vegetables with potassium include tomatoes, avocados, cucumbers and oranges. And of course, the good ol’ banana.

4. Broccoli Might Reduce Cholesterol in Dogs

Cholesterol is something that can slowly build up in your dog’s system very silently. It’s something that vets don’t test for or diagnose as often as they should. The medical condition Hyperlipidemia is often overlooked, but could cause damage as your dog ages.

Hyperlipidemia occurs when there is an elevation of blood lipids (cholesterol) in dogs. This is actually quite a common phenomenon with dogs and could cause other health problems later on in life.

The good news is that broccoli is likely able to lower cholesterol in dogs. In fact, Broccoli contains a lot of soluble fiber, which will draw out the cholesterol from your dog’s body. A few pieces of broccoli every now and then should combat the slow buildup of cholesterol over time.

There are many other fruits and vegetables with high soluble fiber to battle high cholesterol in dogs. Just to name a few, there are apples, strawberries, pineapples, oranges, beans and several types of nuts.

5. Broccoli Has Anti-inflammatory Properties

Among all the health benefits that broccoli provide your dog, this may be the most useful for them. An old dog may have some joint damage after being active for so many years. The same goes for an active dog or working dog breed that is continuously on the move.

A few pieces of broccoli can actually provide amazing anti-inflammatory by slowing down damage to joints. A property in broccoli called sulforaphane can potentially help your dog that suffers from arthritis by blocking the enzymes that cause the joint destruction.

In addition, the omega-3 fatty acids in broccoli have been known to help with the regulation of inflammation. This makes broccoli a great vegetable for battling arthritis and reducing inflammation.

However, don’t start using broccoli as a method for treating this medical condition in your dog this instant. Always consult with your veterinarian before using broccoli as a means to battle these medical conditions.

3 Potential Risks of Feeding Dogs Broccoli

Inherently, broccoli is not poisonous or toxic to dogs. However, this doesn’t mean that we should feed our dogs broccoli without any precautions.

There are potential side effects and risks that your dog may experience from eating broccoli. The risks are higher if you feed them more broccoli than they should be eating.

1. Broccoli May Cause Upset Stomach in Dogs

The reason why there’s a high risk when overfeeding broccoli to your dog is because of the substance called Isothiocyanate. This substance found in broccoli can lead to more serious health problems such as gastrointestinal irritation. Or in other words, severe upset stomach.

It’s recommended that no more than 5% to 10% of the dog’s diet can be made up of broccoli. Any more and they may experience Isothiocyanate poisoning. Depending on the size of the dog, 5 to 10% of their diet isn’t that much.

Regardless, it’s important to monitor closely how much broccoli a dog is given. In addition, you should closely observe your dog after consumption for any behavior changes. If your dog is feeling lethargic (lack of energy), he may be experiencing an upset stomach.

2. Extreme Broccoli Consumption Can Be Fatal in Dogs

Isothiocyanate poisoning in dogs should not be taken lightly. There comes a point when the excess in the substance can potentially become fatal. If your dog consumes broccoli at 25% of their daily diet, they may be at serious risk. The toxicity from Isothiocyanate could indeed be fatal at that point.

If your dog accidentally consumes a large quantity of broccoli, it’s important to get them immediate help. Waiting for your dog to show symptoms of poisoning may be too late. Consult with your local veterinarian right away in this situation.

3. Broccoli May Cause Diarrhea in Dogs

A single cup of broccoli contains an amazing 21% of a human’s daily value recommendation. Humans need fiber for proper bowel functioning, but dogs don’t need as much fiber as we do. There’s a reason why a dog’s diet consists mostly of protein.

This is not to say that dogs can’t benefit from fiber. A little fiber can be good for them as it’ll loosen up their stool a bit. However, too much fiber can cause drastic changes in your dog’s stool habits, such as diarrhea.

Always inspect your dog’s bowel habits immediately after the consumption of broccoli. If you see unusual habits like diarrhea (or constipation), stop the broccoli feeding.

How Can Dogs Eat Broccoli?

Most owners will likely feed their dog broccoli straight from the super market. While the convenience may be a little tempting, we strongly suggest you don’t. Just like with us humans, there are ways to properly prep broccoli for your dogs. Follow the simple steps below!

Wash Broccoli Thoroughly

It’s important to thoroughly wash the broccoli before giving them to your dog. There can be a lot of bacteria and pesticide on the vegetable straight from the grocery store. Although a dog’s stomach can handle bacteria much better than ours, the pesticide can be very detrimental.

I have heard of cases where dogs go into seizures after accidentally consuming raw fruits and veggies with pesticide. It may not be very common, but it could happen. Better to be safe than sorry.

Remove the Broccoli Stem

Most of the Isothiocyanate is contained in the head of the broccoli and not the stem. However, it’s recommended that dogs only eat the head of broccoli. Many parts of fruits and vegetables pose a choking hazard for dogs, including the stem of broccoli. In addition, the hard stem may cause blockage in your dog’s intestinal tract.

Observe Your Dog

If this is the first time your dog is eating broccoli, it’s especially important to monitor them for at least 24 hours after consumption. Look out for changes in both stool habits and behavior. If they’re not feeling like themselves, cease the broccoli feeding. If symptoms persist throughout the day, consult with your vet right away.

Limit the Broccoli

Remember that too much broccoli can become a real threat to your dog. Broccoli itself is not poisonous to them but can become lethal without moderation. You can start off with just a few broccoli heads for your dog. A larger dog can consume more, but keep in mind that consumption should not exceed 10% of their diet. Anywhere around 25% and it could potentially put their life in jeopardy.
