Dogs that have bad breath most often suffer from periodontal disease, although sometimes diabetes mellitus or gastrointestinal issues are to blame. A dog’s mouth contains several types of bacteria that create plaque on teeth when they interact with food particles. Left untreated, plaque and tartar buildup can lead to more serious problems, such as tooth decay and even jaw deterioration.
The best way to treat periodontal disease and get a handle on bad dog breath is with a veterinary dental exam and cleaning. However, you can do a lot to prevent or even reduce bad breath. For example, you can brush your pet’s teeth using special veterinary toothpaste and tools. In addition, you can put additives in the pet’s water that combats plaque buildup. Also, there are treats and toys available to help keep teeth clean. You may also want to explore prescription diets meant to reduce the risk of plaque buildup
If you are concerned with your dog’s breath, have a conversation with your veterinarian to learn more about which of these options is best for your situation.
