Giving your dog a carrot to chew on is an ideal way to keep his breath fresh and healthy.
The high acid in lemons can help to kill bacteria and serve as a natural deodorizer as well. Add few drops of lemon juice into your dog’s water bowl.
Mint might be another natural remedy to promote healthy digestion and soothe the stomach and stop acid from reaching the mouth to cause bad breath. Mint, as well as other herbs, contains natural properties and the ability to promote good digestion.
