inflammation of the gums

Periodontal Disease is defined as an inflammation and/or infection of the gums and bone around the teeth. Periodontal disease is the most common disease found in the dog and will affect more than 8 out of 10 dogs three years of age and older. The prevalence of periodontal disease in the dog increases with age but also decreases with increasing body weight; therefore, toy and miniature breeds are more severely affected.
