Manually brushing your dog's teeth is the most effective in-home dental health practice to reducing plaque and tartar build up on your dog's teeth. Arm & Hammer chicken-flavored toothpaste may help your dog look forward to getting their teeth brushed. This dental kit comes with a double ended toothbrush with two different size heads, so it's great for brushing large and small mouths. It also comes with a finger brush, as sometimes you may find it easier to use your index finger to reach certain spots. Regular brushing can ward off bad breath, gum disease, and other mouth infections.
