    Optimal therapy of any serious or persistent medical condition depends on establishing the correct diagnosis. There are numerous potential causes of halitosis and before any treatment can be recommended, it is important to identify the underlying cause. Initial therapy should be aimed at the underlying cause. This treatment may include:

  • Home Care

    Home care recommendations will depend on the underlying cause of the problem. Some steps that you can take to help eliminate your dog’s bad breath include:

  • Brushing your dog’s teeth daily. Tooth brushes/finger brushes and special toothpastes are available from your veterinarian.
  • Spraying 0.12 percent chlorhexidine (prescribed by your veterinarian) into your dog’s mouth once a day for seven to fourteen days.
  • Following dietary considerations recommended by your veterinarian. Special diets that may be beneficial include Hill’s Prescription Diet T/D® or Eukanuba Restricted-Calorie Rewards®.
  • Evaluation by your veterinarian if the bad breath persists.
