Dogs can brush their teeth. To brush your dog's teeth, use a special toothbrush and toothpaste, and gently scrub the outside of your dog's upper and lower teeth. Developing a good habit of brushing your dog's teeth can prevent many oral problems. Healthy teeth should be intact, naturally white and free of tartar.

Notes on brushing your dog’s teeth:

1. Buy toothpaste, toothbrushes, dental floss, etc. specifically for dogs. Never use human toothpaste. Toothbrushes for dogs.

2. It is best to start brushing your dog’s teeth 2 to 3 times a week when he is 6 months old. If you persist for a long time, you will definitely get the ideal care effect.

3. Before brushing, you can use gauze or finger cots to gently massage the dog's teeth and gums, so that the dog can gradually get used to the feeling of brushing before using a toothbrush.
