For owners who prefer a more natural diet, you can formulate one from ingredients purchased at the grocery store. Such diets may include raw chicken necks, ground up along with the raw bones for a smaller dog like your Maltese, chopped vegetables, cooked beef or chicken, boiled beef liver, cottage cheese and a vitamin supplement. Dr. Tamara Hebbler, a veterinarian with a holistic practice in California called Healing Hope, believes raw foods are best for dogs and a cooked diet of any kind is less desirable. A raw diet usually consists of about 65 to 85 percent meat, 5 to 10 percent organ meat, 20 to 30 percent raw vegetables, up to 10 percent cooked grains or potatoes, and up to 5 percent fruit and nuts. If you choose either a raw diet or to cook food for your Maltese, always follow food handling precautions such as keeping the ingredients refrigerated and always clean up with hot, soapy water.
