Causes Of Stinky Breath In Canines

Dental/Gum Disease

Halitosis in dogs often occurs when pooch has a dental condition. In most cases, gum infection or tooth decay causes a foul odor. You can notice the first signs when you lift your pet’s lip.

If his gums are red and inflamed, then he might be suffering from a gum infection. On the other hand, build up tartar might indicate the tooth decay. Therefore, annual checkups are necessary, to prevent dental disease.

Oral Tumors

Gums and teeth aren’t the only cause of concern when it comes to halitosis. The oral tumor is another potential threat. In some cases, teeth grow too fast, and blood vessels fail to follow their progress.

This causes dead areas to appear. Bacteria then takes over the dead areas, and it’s the reason why foul odor happens. This can later result in an oral tumor. You should be able to notice discolorations in your pet’s mouth.
