Jowls protect a dog’s mouth from injuries.

When a dog is swimming, jowl muscles help him keep his head above water.


Also, jowls come in handy during fights to protect the lower jaws.

Diseases that affect dog jowls

disiese that affect dog jowl

If a jowled dog does not keep proper hygiene, the mouth becomes a breeding ground for germs.

With time, inflammation can develop around the mouth which escalates to disease.


Common mouth diseases in dogs with big jowls include;

  • Oral papillomavirus
  • Inflamed jowl
  • Dog lip fold dermatitis


Oral papillomavirus

This is a mouth disease that commonly affects dogs that are two years and below.

It is caused by the papillomavirus which causes tiny benign tumors in the folds of the jowls.


Oral papillomavirus is contagious and can be passed through direct contact from dog to dog.

Symptoms of oral papillomavirus manifest as tiny pinkish tumors clustered around the jowls, gums, throat, and tongue.

If left untreated, the tumors become painful and cause bad breath in dogs.


Some dogs are asymptomatic to this infection which can make the disease hard to detect.


Inflamed jowls

Inflamed jowls become red and swollen.

They are also painful to touch especially if they have an abscess.


Dental diseases like periodontal disease can cause inflamed joints.

There are pet allergies that can cause inflammation of the gums and jowls as well.


Lip Fold dermatitis

Dogs with big jowls are also vulnerable to lip fold dermatitis.

This is a condition that affects the mouth and in some dogs the vulva and tail as well.


The affected area appears swollen and reddened.

The skin in that area feels dump as well.


If the infection escalates, a bad odor may develop in the skin folds.

The only way to treat lip fold dermatitis is to clean the infection daily at home.
