Cats are carnivores and so cannot live without meat in their daily diet. Dogs, however, are omnivores and so are able to eat a wide range of vegetables and some fruit. (PHOTOGRAPHY iSTOCK.)

While many conventional doctors discourage clients from feeding dogs and cats ‘people food’, I believe fresh organic food contributes to improved health in my patients. While this applies to both cats and dogs, many cats don’t seem to relish produce as much as dogs, but it’s worth experimenting.

Fruit and veg are generally low in kilojoules, which means they make great treats for pets on a diet. While vegies can be consumed raw, steaming or sautéing are better alternatives. I don’t suggest a particular amount, as long as the vegetables or fruits make up no more than 20-25 per cent of a dog’s diet (if you are using a processed natural food) or 40-50 per cent of a homemade diet.


Most dogs like carrots, either whole or cut into pieces. The tops of carrots can be fed whole to pet rabbits and rodents, or chopped fine and used as a topping on dog food. One compound found in carrots, falcarinol, has anti-cancer properties; another, betacarotene, promotes healthy vision and also functions as an antioxidant to fight free radical cell damage. Carrots may also reduce the risk of heart disease.


Many owners give their dogs varieties of green or string beans. Bean pods (including the seeds) can be used whole or cut into small pieces. Health benefits of green beans may include decreased blood cholesterol and glucose levels, because of their fibre; and improved heart health, due to their antioxidant, folic acid and vitamin B6 content.


Broccoli is one of my favourite recommendations, especially for pets with disorders of the immune system, including cancer. Broccoli contains indole-3-carbinol and sulforaphane, compounds that help control cancer by promoting ‘good’ hormone levels (especially oestrogen levels) and increasing the level of enzymes that help prevent cancer formation.


Any dark green leafy vegetable is good for pets. Some dogs will eat the greens after they are cooked. Steam, sauté or blend an assortment with water or organic meat broth and pour it on the pet’s food. High levels of antioxidants in greens help prevent increased oxidation and cell damage, which can be responsible for cancer, and chronic inflammatory diseases such as arthritis.


I think of fruit as more of a dessert than a main ingredient; therefore, I recommend no more than 10-15 per cent of the diet contain healthy organic berries. Health benefits of berries are due to their high antioxidant content. Berries, especially blueberries and blackberries, are helpful in fighting any disease in which oxidative stress and inflammation play a role, including arthritis, allergies and cancer.

Foods to avoid

While most pets can eat pretty much anything you grow, there are some things to avoid due to potential toxicity. Cats and small dogs are sensitive to some of the chemicals in onions and garlic, as these foods can cause red blood cell damage leading to anaemia. All pets should avoid onions. Garlic has many health benefits (antibacterial, anti-blood clotting, immune system support), and I like my patients to have small amounts if their owners desire. I recommend one small clove per 5-11kgs of body weight per day. Regular blood testing (every three to six months) can detect anaemia, which is unlikely at this dosage. Grapes and raisins can cause kidney failure in dogs and should be avoided. But all our pets have different needs so always check with your own vet.
