Bad dog breath is a common condition that can make some pet parents hesitate when getting close to their dog. The American Veterinary Medical Association named February as National Pet Dental Health month; we’re creating awareness about it by talking about causes of bad dog breath, many of which are connected to dental health. Some causes are rather harmless, such as your dog just ate some cat poop, while others causes could be a sign of a serious underlying health condition. While smaller breeds, older dogs, and breeds with short snouts are more prone to having bad breath, a healthy dog shouldn’t have chronic bad breath. In this article, we will explain the common causes of stinky dog breath, the connection between poor oral health and disease, prevention tips, and available treatment options.
