Lumps under the chin are a common spot for abscesses to form. Note that differentiate between ‘lump’ (which can have many causes) and abscess (an infection that is pus that forms into a lump). Abscesses (not all lumps) are infection pouches that can spread inside, rupture, enlarge and squeeze the neck, limiting the guinea pig’s capacity to breathe.

Common causes of these are teeth growing rapidly that push other teeth within the mouth of the guinea pigs, or infection entering the mouth that causes abscesses or swollen lymph nodes, tumors, cysts, or fatty lipomas. The best treatment is via surgical operation (Not for all lumps, but likely for tumours and some abscesses).

Infections that enter the tissues through the mouth or the skin are the most common causes. 

Guinea pig teeth are known as open rooted because they develop continuously. This means that, compared to other animals, they are more susceptible to infection invading the tooth root and jaw, forming lumps.

Guinea pigs are also prone to mouth scratches and abrasions, which can lead to infection beneath the skin. These can lead to abscesses, and in the worst-case scenario, the infection can spread to the lymph nodes which are often in their neck.

How To Treat Lump/ Abscesses

The best way to treat Lumps or Abscesses is via surgery. So it is best that once you have noticed that your guinea pigs have lumps, it is imperative to have them checked up immediately.

What Can Happen If Left Untreated?

Lumps under the chin are extremely uncomfortable, and painful for guinea pigs, and if left untreated, the tendency of the lump is to increase in size and effectively block out air pathways of the guinea pig resulting in difficulty of breathing, and even death.

Other known cases of untreated lumps and abscesses are the spread of bacteria on different body parts of the guinea pig, causing them more discomfort and other health issues, especially cancer.

This depends on the type of lump and how fast it spreads to other body parts or block out the air pathways of the guinea pig.

If the tumor is cancerous, only a few weeks after diagnosis, but if it’s not cancerous, it takes a few years depending on the level of care received by the guinea pig.

However, It causes much discomfort for the guinea pig so it is still important to have a proper veterinarian diagnosis.

Guinea pigs after surgical treatment usually need one rund of antibiotics or depends on the prescription of the vet. Do not purchase any antibiotic, and listen to the vet and do not stop treatment until your vet says so.
