What is a Sebaceous Cyst
Sebaceous cyst on dogs are easy to understand, they are formed when excessive sebum is produced or trapped in a nearby hair follicle leading to an obvious lumpy-like growth.
These cysts can appear almost anywhere on the body but are mostly seen on the head, fore limbs, neck and trunk. They take the form of soft to hard squishy grey, white or bluish lumps.
The Sebum acts as a natural lubricant, nourishing the hairs or furs and moisturising the skin, preventing it from getting dry, and protecting it from infection and bruises.
These singular-appearing lumps could sometimes burst and release a thick yellowish or grey substance. The sebaceous cysts are usually not cancerous or life threatening but could be when not taken care of.
“About 50% of Sebaceous growths are technically not tumors at all and are grouped as excessive growth of the sebaceous gland tissue”, - Wendy Brooks.
Sebaceous Types of Cysts on Dogs
When Sebaceous cyst on dogs bursts, they become prone to secondary infection which when left untreated could get infected and result in more complications. Here are a few types of sebaceous cysts that could occur in dogs:
Sebaceous Adenoma
This type of Sebaceous cyst usually looks crusty and is found on the head and eyelids of older dogs. This crust could be infected if it oozes pus with a yellowish coloration.
The English Cocker Spaniel, Husky and Samoyed are mostly the predisposing breeds to this type of Sebaceous cyst. My neighbor had two huskies at one time and complained that of all the breeds of dogs she had owned, only the huskies had experienced the sebaceous cyst formation, this might not be a coincidence.
Sebaceous Gland Hamartoma
The Sebaceous gland hamartoma is a tumor of the sebaceous gland which is usually noticeable at birth. They could appear as circular or elongated, spanning about 2 inches in length.
This congenital condition usually results in a cyst formation on the scalp of the dog and is usually accompanied by other symptoms like itching and biting at the cyst location.
Sebaceous Gland Overgrowth
An overgrowth of the Sebaceous gland could result in cyst formation on the head or abdomen. Older dogs are commonly prone to this condition due to a concurrent gland tumor or an underlying infection.
The Welsh Terriers, Manchester and Wheaton are highly susceptible. Old age and hormonal imbalance and even UV rays can result in this type of condition.
With the help of the Petcube GPS Tracker, you can keep a close eye on your dog, making sure it doesn’t come in contact with any trigger such as UV rays in sun lamps or even too much direct sunlight.
Sebaceous Gland Adenocarcinoma
This is a more advanced type of sebaceous cyst, it includes a combination of a tumor and overgrowth of the Sebaceous gland which has affected surrounding lymph nodes and even the lungs.
Middle aged to older dogs are more predisposed to this condition. This type of Sebaceous cyst is Malignant and should be taken seriously. Breeds like Terriers and the Cocker Spaniels are highly predisposed.
What Cause Sebaceous Cysts on Dogs
The cause of Sebaceous cysts in dogs ranges from minor injury to an allergic reaction or a hormonal imbalance which determines how severe the cyst formation would be. Some of the known causes of Sebaceous Cyst formation in dogs includes one or more of the following:
Allergic skin reaction
Your dog may experience some allergic skin reactions which could lead to cyst formation. These reactions may be due to drug toxicity or chemical toxicity.
Sebaceous Adenitis
In a case of Sebaceous Adenitis, the body exerts an inflammatory process against the Sebaceous gland causing loss of hair, crust and scales formation which in turn leads to secondary bacterial infection.
Sebaceous cyst in this case has been observed to result due to autoimmune response of the body against the Sebaceous gland coupled with a defective sebum production.
Inflamed Hair follicle/Follicular blockage
Inflamed hair follicles also known as folliculitis is as common as Sebaceous cyst formation with similar symptoms.
An inflamed hair follicle may have resulted from an infection with bacteria. Most of the time, when a hair follicle gets infected, inflammation takes place to resolve the underlying problem. In this process, sebum is produced in excess resulting in cyst formation on top of the skin.
Genetic Disorder
Though uncommon, Sebaceous cyst formation has been linked to genetics after identifying sebaceous cyst lesions on newly born puppies. There could be a chance genetics had a role to play.
Insect bite/ Insecticide Toxicity
An insect bite, depending on how venomous it is, could result in a sebaceous cysts formation on the skin. Likewise, insecticide can cause serious allergic reactions and could lead to cyst formation.
Sebaceous Cysts Symptoms in Dogs
The symptoms of Sebaceous cysts in Dogs can present in different forms depending on the cause and type. Some of the common symptoms of Sebaceous Cysts in Dogs are:
- Itching at the area of Cyst formation.
- Observable raised inflamed area of the skin.

An friend of mine who had a Cocker Spaniel had observed her dog itching at her flank aggressively, we took a closer look at the flank and found out that she had gotten an infection which might have resulted from a Sebaceous cyst left untreated.
