While vegetables can be consumed raw, steaming or sautéing are better alternatives. Spice things up with salt, pepper, turmeric, lemon, or just about any seasoning you like. There are exceptions, however—see "Foods to Avoid" below.

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 anticancer properties; another, beta-carotene, 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 fiber content; and improved heart health, due to their antioxidant, folic acid, and vitamin B6 content.

Broccoli is one of my favorite recommendations to pet owners, 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 estrogen levels) and increasing the level of enzymes that help prevent cancer formation.

Dark Leafy Greens
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 to 15 percent of the diet contain healthy organic berries. Health benefits of berries are due to their high antioxidant content. Berries, especially blue-berries 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 anemia. 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 10 to 25 pounds of body weight per day. Regular blood testing (every 3 to 6 months) can detect anemia, which is unlikely at this dosage. Grapes and raisins can cause kidney failure in dogs and should be avoided. (Here are more foods that you should avoid feeding your dog.)
