Dear Daisy Dog: When I chop vegetables for soups, stews and other dishes, I invariably drop some pieces onto the floor, where my dogs immediately devour them. I worry that some of the veggies may be toxic. Which should I be especially careful about? Daisy Responds: Most vegetables are safe for us dogs – except onions, garlic and chives. They can damage red blood cells and cause anemia, so make sure they don’t fall from your cutting board. If one of your dogs has a history of calcium oxalate bladder stones, it’s best to avoid oxalate-containing vegetables, such as leafy greens (including rhubarb), beets and potatoes. The root of the jicama is safe for dogs, but the seeds and other above-ground parts of the plant are toxic. Because the root is usually sold by itself, you shouldn’t have a problem unless you grow jicama in your garden. Some vegetables, such as cauliflower, produce gas, so you should be careful not to let large quantities drop to the floor. Otherwise, most vegetables are tasty, low-calorie, nutrient-rich, high-fiber treats your dogs can enjoy.
