Bad breath in a dog is often dismissed simply as “doggy breath.” But in fact, it may very well signal periodontal disease, which is the most common ailment suffered by dogs and cats over 3 years of age. Preventing periodontal disease can result in longer, healthier lives for our pets. Unfortunately, pet owners often ignore dental care. One survey notes that just 1 out of 10 owners make sure their pets’ teeth are cared for. Although dogs and cats rarely get cavities, the plaque and tartar that do form can cause gingivitis and periodontal disease. This can lead to tooth decay, bleeding gums and tooth loss. The bacteria can also travel through the bloodstream and eventually damage your dog’s major organs. Proper pet dental care begins with a trip to the veterinarian for a dental exam, which should be done once a year. If your vet sees plaque or tartar buildup, a cleaning may be necessary.

Here is an example of a dog that has dental disease:
