Key Points

  • Broccoli can be a great nutrient-dense vegetable to feed to your dog, containing many important vitamins and minerals
  • As with anything, too much of a good thing can be bad. There are important rules to follow when feeding your dog broccoli
  • Be aware of the possible adverse effects of feeding too much broccoli to your dog
  • Always wash florets to remove bacteria, and cut the stems into small pieces to avoid choking

  • Don’t feed broccoli to young puppies


There is great emphasis these days of healthy eating among humans which can only be a good thing. One much promoted ‘superfood’ is broccoli that is a staple vegetable often included in family dinners, and so you may have often wondered, is broccoli safe to feed to dogs? And does broccoli have the same health benefits as it does in humans? The answer is yes, broccoli can be a great addition to your canine friend’s diet, but in moderation. Let me explain why.

When broccoli is bad for dogs?

The broccoli florets contain a compound called Isothiocyanate, which is also found in all cruciferous vegetables like cabbage, cauliflower and kale. In humans Isothiocyanate is considered to be very beneficial as it functions as a strong anti-inflammatory. However, the same is not necessarily true of dogs – in excessive amounts this substance can cause irritation to your dog’s gastrointestinal system resulting in gas build up, stomach upset, diarrhea and even blockages.

It is safe to feed either cooked or raw, but if you want to feed your dog raw broccoli be sure to wash it thoroughly beforehand as it can be a source of harmful bacteria such as salmonella. Even though dogs are more resistant to these nasty bacteria species, they are not immune to them and an overwhelming infection can result in vomiting, fever, dehydration and lethargy should they be ingested.

The broccoli stems, although completely edible, do pose a choking hazard if consumed in large chunks as they are very hard. Be sure to cut broccoli into smaller pieces before offering it to your dog as it has been known to cause obstruction in the esophagus .

I would avoid feeding broccoli to puppies completely as their digestive system is still developing and is very sensitive to new foods. Overdoing green vegetables in growing animals may increase the risks of gastrointestinal blockage, leading to an unwanted trip to the vets.

Be aware that in some rare cases, your dog may have a genuine food allergy to pineapple. Symptoms of allergic reaction can range from excessive diarrhea to itchy skin and even anaphylaxis (difficulty breathing). If your dog has a reaction like this, take them to your local vet immediately.

If your dog is generally an allergic or sensitive dog, this allergy medicine for dogs contains a powerhouse of natural ingredients and may help provide relief from other seasonal and environmental allergens.

Is broccoli healthy for my dog?

Broccoli is packed full of micronutrients that are essential in a healthy diet. It is rich in vitamin K which is vital for improving bone density and strength which allows your dog to play for longer and may improve a dog’s mobility as it ages. Vitamin K is also a crucial part of the coagulation process that ensures blood clots form correctly if your dog has an open wound. Broccoli also contains high amounts of vitamin C which improves immune function, helping them to fight off infectious disease carried by viruses and bacteria.

Broccoli is high in minerals such as magnesium, potassium and sodium which are all involved in many normal body processes. Magnesium is crucial for proper hormone function and is involved in the proper absorption of many other micronutrients. Potassium is extremely important for proper nerve function and muscle contraction.

As mentioned before too much broccoli can cause gastrointestinal upset or blockages, and this is often due to the high fibre found in broccoli. However, when fed in moderation, this fibre is essential for normal bowel movements and healthy digestion.

Broccoli is also great for your dog’s dental health, especially if fed raw (but remember to wash it). Crunching on the broccoli stems helps to break off any plaque that may have accumulated on your dog’s teeth or gums. But remember only feed in small pieces. However, the stems are very hard and so I would only recommend this if your dog hasn’t been diagnosed with any underlying or severe dental issues, because this crunching could do more harm than good.

These supplements for dogs contain ALL the nutritional vitamins, minerals, antioxidants and essential omega-3 fatty acids that will help your puppy or senior dog to stay healthy, happy and in great tail-wagging condition!

How much broccoli can my dog eat?

Dogs are omnivores meaning that, much like us, they derive nutrition from both animal and plant sources. However, I would recommend that vegetables make up no more than 25% of your dogs’ overall diet, otherwise the excessive fibre may lead to the gastrointestinal issues mentioned previously. In addition to this, if you are using vegetables such as broccoli as treats then these shouldn’t make up more than 10% of your dog’s calorie needs for the day, as too much of a good thing can lead to weight gain and obesity.

As with introducing any new food to your dogs’ diet, start slow to ensure that broccoli agrees with your dog, and monitor for any signs of stomach upset.

Broccoli can be served raw or cooked, and always cut it into small pieces before offering it to your canine friend. And keep it as natural as possible, avoid cooking broccoli with seasonings, oils and other ingredients that may cause issues
