Brushing your dog's teeth is an integral part of keeping him healthy. It won't just prevent him from getting cavities and periodontal disease; it may also prevent him from having his immune system, kidneys and heart attacked by bacterial infections. The Dog Owner's Home Veterinary Handbook suggests cleaning dog teeth three times a week at least to stop problems before they start. While there are special toothpastes formulated specifically for dogs, you can also use baking soda to create homemade dog toothpaste that is almost as effective.
Make a paste by mixing a tablespoon of baking soda with a teaspoon of water. If the mixture is too thin, add small amounts of baking soda until it thickens.
Settle your dog in front of you or on your lap. Position him so that you can control him while you brush his teeth.
Dip a toothbrush in the baking soda paste.
Lift your dog's lips until his teeth are exposed.
Hold the toothbrush parallel to the dog's gums and begin brushing his teeth with circular strokes.
