Why your dog should eat fruits and veggies

Most people think of dogs as meat-eaters — and of course meat needs to make up a large percentage of their diet. But fruit and veggies are also beneficial to canine health and well-being.

When it comes to including vegetables and fruit in the canine diet, people have different opinions. Some think it’s unnecessary; others feed small amounts (up to 10% to 15% of the total diet); while still others give their dogs plentiful quantities. While vegetables and fruit may not be classified as “essential” for dogs, they’re clearly very beneficial. Evidence suggests they can provide the same benefits to dogs as they do to humans, and can help prevent cancer, cardiovascular problems, autoimmune diseases, metabolic issues, and more. Vegetables and fruit contain an abundance of valuable nutrients, including vitamins, minerals, enzymes, phytonutrients, and antioxidants.

Let’s look at the role of vegetables and fruits in the canine diet, and how you can add them to your own dog’s meals.

Dogs are “facultative carnivores”

Although dogs are generally recognized as carnivores, like their wolf ancestors, they are actually what are called “facultative carnivores”. This means they can and will utilize plant matter as part of their predominantly meat-based diet. A study on wolf scats collected between 1992 and 2005 reported a content of up to 7.8% plant matter during the summer months. This plant matter included vegetation and berries and was believed to come from intentional consumption.

Adding fruits and veggies to your dog’s diet

While dogs can’t digest cellulose, the main substance in plant cell walls, they do digest vegetables and fruit and will readily eat them. And the benefits of the phytonutrient antioxidants provided by these foods are significant. Studies have shown that dogs with certain cancers have reduced antioxidant levels. Antioxidants have also been found to prevent cognitive decline in aged dogs. Additionally, phytonutrients can slow down oxidative damage and other effects of aging.

All this means that vegetables and fruit (preferably fresh and organic) are an invaluable addition to a dog’s predominantly meat-based diet. Quantities will depend on the individual dog, his breed, and particular health concerns. Start with small amounts and experiment with different fruits and veggies to see which ones your dog likes best.

  • Vegetables can be fed raw, but I usually recommend lightly steaming them, particularly when it comes to cruciferous vegetables, which contain goitrogenic compounds that may disrupt thyroid hormones. Lightly steaming these veggies helps deactivate these compounds.
  • It is advisable to remove pips and pits from fruit, and caution is also advised with some of the skins or tough rinds found on some fruit and vegetables.
  • Always keep in mind that not all vegetables and fruit are safe for dogs. In particular, onions, grapes, and raisins should be avoided.
