Keeping your dog's teeth clean can help keep your dog healthy. Use a soft toothbrush. A child's toothbrush for small dogs is ideal; an adult size should be used for larger dogs.
Use toothpaste formulated especially for available at pet supply stores or your veterinarian's office.
Begin by only brushing the outside surfaces of the teeth. When your pet has adjusted to this, add the inside surfaces between the teeth and tongue.
