Halitosis is a bad, offensive odor coming from the mouth – usually called bad breath. This could be caused by a number of conditions – most prominent being periodontal diseases, a disease resulting from bacteria in the mouth. Plaque and cavities could also be caused by bacterial infections.
Brachycephalic breeds are the most prone to periodontal and other mouth diseases due to their teeth being so close together in the mouth.
Symptoms other than the bad breath would relate to the type of disease causing halitosis. If the cause is a disease of the mouth, other symptoms like pawing at the mouth, inability to eat, loose teeth, and excessive drooling may be seen.
