Toothbrushes available, include traditional brushes with bristles, finger brushes, and three head brushes to get hard to reach areas of the mouth. Choose a toothbrush that is appropriately sized for your dog's mouth and comfortable for you to use. Some dogs may prefer one type of brush over another, so it may take some experimentation to find the right one for your dog. Also, make sure you are comfortable and confident using the style of toothbrush chosen.
