As humans, we know the value of consuming vegetables. They are packed with nutrition, vitamins, minerals, fiber and overall goodness that our bodies need. Did you know there are also many vegetables dogs can eat, which have also been proven in studies to improve dog’s overall health?
Just walk down the produce aisle of your local grocery store and you will see all manners of vegetables, often hailing from all corners of the world. The beautiful thing is that most vegetables are as good for your dog as they are for you, but some veggies are much better for dogs than others.
But aren’t dogs carnivores?
While dog’s aren’t carnivores by definition, the majority of a dog’s diet should still come from meat of animals. However, they also need nutrients that are not easily found in the flesh and organs of animals. While it is true that dogs can survive on largely meat-based diet, dogs do supplement that diet with plant-based foods like vegetables and fruits.
We’ve previously written about dogs going vegan, which in theory may work, but isn’t a good option. One of the better studies on dog’s vegetarian diet vs meat-based diet have observed the pros and cons of each (1). The conclusion researchers came to is that the mixture of both worlds, meat and plant foods, may be the best for dogs’ health.
For dogs, this is not just an opportunistic form of feeding, but is one born out of necessity and through domestication over the last 10,000 years. By feeding your dogs certain vegetables in moderation, you are positively affecting their health.

The verdant florets of broccoli are unmistakable. For humans, broccoli often serves as a most welcomed side dish, or smothered with cheese and served as a main course. For dogs, it is best served as a natural treat and in small portions only.
This absolute need for moderation is due to isothiocyanates, a compound found within the flesh and florets of broccoli that has been known to cause gastric irritations when consumed in high amounts.

Also known as alpha tocopherol, is often associated with keeping a healthy coat on dogs; however, it is due to its effects on the central nervous system that makes it such a valuable attribute of broccoli.
Alpha tocopherol has been shown in studies (5) to have a positive effect on the peripheral nerves as well as non-nervous tissue in dogs. This makes broccoli one of the few vegetables dogs can eat to directly influence a canine’s nervous system. So, it seems that the effects of vitamin E go beyond skin deep, but the amazing qualities of alpha tocopherol do not stop there.
More evidence shows that dogs given concentrations of vitamin E (6) exert a higher degree of endurance. This makes broccoli, and the vitamin E it contains, a convenient and cost effective means of providing working dogs and sled dogs, in particular, a means to boost their endurance and output, and we discussed this in our science-based canine athlete nutrition article in more depth.
Limited evidence has also been displayed in using alpha tocopherol to cure the muscular dystrophy of malnourished pups. Although, it should be mentioned that this has only shown to be effective before symptoms become severe. Studies with rats (7) and dogs (8) have found that broccoli can positively influence the microbiota of animals, similar to that when using probiotics for dogs.
Furthermore, the dark green color of broccoli is due to the high amounts of chlorophyll trapped within its cells, which has been shown to display (9) protective properties against exposure to cancer-causing factors. This true for both humans and dogs.
This effectively turns broccoli into a cancer fighting food, as chlorophyll and its derivatives are considered antioxidants, antimutagenics, mutagen trappers, modulators of xenobiotic metabolism and inducers of apoptosis.
