Bump on Dog Eyelid, Cyst, Stye, Growth and Tumors

Bump on dog eyelid

The eyelid protects the internal structures of the eye and is prone to bumps and growths. A bump on dog eyelid can be a mere infection that clears up with time or it could be something as serious as a malignant tumor. We explore the causes, symptoms and treatment options for various types of bumps occurring on the eyelid.

Bump on Dog Eyelid

A bump on dog eyelid may appear as a lump, growth or swelling on its surface or along it’s edges. The bumps stem out from a number of causes. These may be bacterial, viral or fungal infections in which case the bumps clear up once the infection clears. Others may result from tumors that may require surgeries to eliminate. Below are various causes and how to identify them as well as home care and when to see a veterinarian.

Stye on Dog’s Eyelid

Also referred to as hordeolum, styes are as a result of bacterial infections and inflammation around the eyelid. These can appear as a single abscess or multiple ones which are accompanied by swelling along the margins of the eyelids.


A bump on dog eyelid could also be caused by a chalazion. This is almost similar to a stye. When a dog has it, the Meibomian glands in the eye will at times get impacted and blocked. This results in swelling and even rupturing causing a release of oily secretions.

This kind of bump can be treated at home by applying a washcloth that has been soaked in warm water on the affected eyelid. Allow this to rest for about five minutes and repeat procedure three times. The warmth encourages drainage and thus reduces impaction.

Allergic Blepharitis

This is inflammation of the eyelid which is as a result of an allergic reaction. It happens when the eyelid gets exposed to allergens resulting in a rapid onset of symptoms that may include redness of the eyes and swollen bumps on the eyelid. Formation of bumps on dog eyelid may also be as a result of a general reaction to allergens in the body. This could be caused by food reactions, reaction to drugs as well as insect bites and stings. The treatment should include administration of antihistamines.

Bacterial, Fungal, and Parasitic Blepharitis

This is inflammation of the eyelids resulting from bacterial or fungal infections and parasitic microorganisms. When the Meibomian glands get infected by bacteria, there may be abscesses on the eyelid margin. In case the condition affects puppies, it could become severe and result in serious eyelid and facial swelling.

Fungal blepharitis, on the other hand, could see a formation of a ringworm bump on dog eyelid. This, too, could cause inflammation in addition to the crusty lesions and hairless circular rings characteristic of ringworm infestation.

Parasitic blepharitis, on the other hand, occurs when sarcoptic or demodectic mange infests the eyelids. The mites result in the formation of crusty lesions on the eyelids. When this occurs in puppies, it is usually isolated to the eyelids and face.

Getting rid of a bump on dog eyelid resulting from any the types of inflammation requires the elimination of the cause.

Sebaceous Cyst on Dog Eyelid

This is another kind of bump on dog eyelid. Sebaceous cysts develop beneath the skin and have a semi-solid or fluid-filled sac appearance. The cysts may be as a result of blocked follicle opening, inadequate secretion of sebum, trauma, allergic reaction and swollen hair follicles as well as follicular inactivity. In most cases, these cysts are harmless and can be left alone. However, in case it becomes infected or starts to develop into a large bump suddenly, you will be required to see a veterinarian. Infection mostly occurs after the cyst has ruptured leading to inflammation and itchiness.


Also referred to as pink eye in dogs, conjunctivitis is a common cause of swelling on the eyelids. It results from inflammation of the conjunctiva. It can be viral or bacterial. The conjunctiva is meant to be the first line of defense for the eye. The condition manifests as the eyelid lining tries to absorb infection-causing organisms and protect other eye structures. Viral conjunctivitis clears up on its own after a few days while bacterial conjunctivitis can be treated with antibacterial eye drops or ointments. In addition to the swelling, the eyes will appear red, give a pus-like discharge and itch.

Cuterebra Larvae

The Cuterebra fly is known to lay eggs on the margins of the eyelid. Once these eggs have hatched, a larval worm starts to grow beneath the skin. With time, a mass may develop around it appearing like a bump on dog eyelid. There usually is a small hole on the surface of the bump through which the larva breathes.
