Solutions for tartar on dog teeth and bad breath:

1. Use dental cleaning products to brush teeth. There are dog-specific toothbrushes and dental cleaning fingertips, so you can brush your dog's teeth every day.

2. Use dog-specific tooth cleaning water. Feeding your dog dental cleaning water every day can remove bad breath and dissolve dental plaque.

3. Take the dog to the pet hospital for ultrasonic dental surgery. This kind of surgery is suitable for dogs with a lot of tartar. The surgery requires anesthesia and the dog's emotions must be soothed.

4. Buy some teething snacks for your dog. If your dog has tartar on his teeth and has bad breath, it may be dental calculus. You can buy him some teething snacks to alleviate oral diseases.

5. Improve the dog’s diet. Bad breath can also occur if a dog eats food that is not easy to digest or eats too much meat. Owners can balance the dog's diet, feed some fruits and vegetables, and feed probiotics to regulate the dog's gastrointestinal tract.
