If you notice a lump on your dog's eyelid, it's essential to take action right away. A lump on the eyelid can be a sign of a serious underlying condition, such as a tumor or an infection.
It's not uncommon for eyelid lumps to be painless, but if your dog is showing signs of discomfort or pain, seek veterinary attention immediately.
A veterinarian can diagnose the cause of the lump through a physical examination and possibly a biopsy.
What Causes in?
The causes of eyelid lumps in dogs can be quite mysterious, but there are some known factors that contribute to their development. Meibomian gland cysts, for example, occur when oils and debris are trapped in the canals, leading to inflammation and local infections.
Some breeds are more prone to eyelid lumps due to genetically weak eye structures. These breeds include English bulldogs, French bulldogs, Great Danes, Cane corsos, Shar Peis, Boston terriers, Beagles, Cocker spaniels, Lhasa Apsos, and Shih Tzus. Brachycephalic breeds, which have short limbs and "squashed" faces, are also more likely to develop eyelid lumps.

Cherry eye, a type of eyelid lump, is thought to be caused by weak fibers holding the gland in place. This can lead to the gland slipping out of place and sticking out, resulting in a pink or red lump of tissue near the lower eyelid.
The following breeds are more likely to develop cherry eye: English bulldogs, French bulldogs, Great Danes, Cane corsos, Shar Peis, Boston terriers, Beagles, Cocker spaniels, Lhasa Apsos, and Shih Tzus.
Environmental allergies can also contribute to cherry eye in dogs, as allergens can cause an immune system reaction that leads to an increase of cells in the gland, causing it to swell and bulge out from the eye.

Types of Growths
Eyelid lumps in dogs can be caused by a variety of growths, and understanding the types can help you determine the best course of action.
Benign tumors are the most common type of eyelid growth in dogs, accounting for over 75% of cases. These tumors are usually located along the eyelid glands or skin and can appear as small growths that enlarge over time.
Malignant tumors are rare but can be cancerous and may cause the cancer to spread to other parts of the body. These tumors should be removed with the help of a vet to keep your dog safe and healthy.
Some common types of eyelid lumps in dogs include meibomian gland tumors, which account for around 60% of all cases. These tumors are usually benign but can be cancerous in some cases.
Melanomas are another type of eyelid lump in dogs, which are cancerous and require aggressive treatment. They can be caused by overexposure to sunlight and can develop from the eyelid skin or pigmented eyelid margin.
Chalazion, also known as a meibomian cyst, is a type of eyelid lump that develops when the meibomian gland opening blocks. This can cause swelling and chronic localized inflammation, and symptoms include a visible eyelid mass, redness, and blepharitis.
Here are some common types of eyelid lumps in dogs:
- Benign tumors (over 75% of cases)
- Malignant tumors (rare, but cancerous)
- Meibomian gland tumors (60% of cases, usually benign but can be cancerous)
- Melanomas (cancerous, require aggressive treatment)
- Chalazion (meibomian cyst, not cancerous)
Diagnosis and Treatment
A veterinarian can diagnose eyelid lumps on dogs by reviewing their medical history and performing a complete physical and ophthalmic examination. They will also perform tests such as fluorescein staining of the cornea and X-rays of the dog's chest to ensure the tumor has not spread.
The veterinarian may perform a punch biopsy or fine needle aspirate (FNA) to examine masses lacking the typical morphology and malignant growths. Eyelid bumps and lumps in dogs are visibly distinct, allowing for a presumptive diagnosis.
The treatment for eyelid lumps on dogs depends on the type and size of the growth. Surgical removal, cryotherapy, and radiation and chemotherapy are common treatment options. The veterinarian will recommend the best course of treatment based on the dog's overall health and the growth type.
Here are some common treatment options for eyelid lumps on dogs:
- Surgical Removal: Wedge resection and blepharoplasty are two surgical options for removing eyelid masses.
- Cryotherapy: Freezing the growth to shrink its appearance and prevent regrowth using a cryoprobe.
- Laser Ablation: Cauterizing small eyelid bumps and lumps using a CO2 laser.
- Radiation and Chemotherapy: Used when the eyelid tumor spreads.
The duration of treatment for a lump on a dog's eyelid is between 10 to 14 days, with surgical treatment resolving immediately. Inflammatory and non-surgical eyelid bumps and lumps in dogs take 10 days to two weeks to heal upon adequate treatment.
Unable to Close
If your dog's eye growth is large enough, it can prevent their eye from fully closing, which is uncomfortable for them and can cause dry eye.
This can be a painful issue for your dog, and it's essential to address it as soon as possible.
The growth may be large enough to rub against the eye or eyelid, causing irritation and discomfort.
In severe cases, the inability to close the eye can lead to chronic eye problems.
Your veterinarian can assess the situation and provide guidance on the best course of action to alleviate your dog's discomfort.

How Vets Diagnose
Vets diagnose eyelid bumps on dogs by reviewing their medical history and performing a complete physical and ophthalmic examination.
The diagnosis of eyelid bumps and lumps in dogs is often straightforward due to their visibly distinct nature.
A veterinarian may perform a test called fluorescein staining of the cornea to rule out ulcers.
X-rays of the dog's chest are also taken to ensure the tumor has not spread.
A punch biopsy or fine needle aspirate (FNA) is used to examine masses that lack the typical morphology or are suspected to be malignant.
Fortunately, the diagnosis of cherry eye in dogs is straightforward, as the growth is easily identifiable.
Vets can examine a dog's eye to determine if a prolapsed gland has occurred, which is a common cause of cherry eye.
Treatment and Surgery
A growth on a dog's eyelid needs to be diagnosed and treated by a vet, even if it's non-cancerous, as it can still cause irritation and discomfort.
The vet may opt for cryotherapy, a procedure where they freeze the growth to shrink its appearance and prevent regrowth, for small and caught early growths.
V-Plasty surgery is an option for larger growths, where the vet removes a small wedge of tissue where the growth is located and stitches the incision back together.
Chemotherapy may be suggested for malignant tumors like melanoma, where the vet prescribes treatment through a pill or injection on an appointment basis.

Eye removal, also known as enucleation, is sometimes necessary when a cancerous eye tumor is large, aggressive, or invasive, causing irreversible damage to the dog's eye.
Here are the different treatment options for eyelid growths:
- Surgical removal: Wedge resection and blepharoplasty are two options, where the growth is removed by making a small V-shaped incision or reconstructing the eyelid.
- Laser ablation: CO2 laser ablation is an alternative to standard surgery, where the growth is cauterized with a laser.
- Cryotherapy: Freezing the growth with liquid nitrogen to make it fall off.
- Radiation and chemotherapy: Used when the eyelid tumor spreads, where local chemotherapy is integral to treating locally invasive eyelid melanomas.
- Medication: Topical antibiotic ointment or eye drops treat infected or blocked glands.
- Anti-inflammatory medications: Recommended for eyelid bumps and lumps in dogs in tandem with antibiotics.
- Warm compresses: Placing a warm compress over the dog's eye helps extract pus and clear gland blockages.
- Enucleation: Removing the whole eye in rare cases where the tumor is large, aggressive, or invasive.
Treatment and Prevention
Treatment and prevention of eyelid lumps in dogs require a multi-step approach. Surgical removal is the only curable therapy for cherry eye, but your vet may begin treatment by prescribing topical anti-inflammatories or suggesting at-home remedies.
Surgery for cherry eye will be performed by an ophthalmologist and usually involves permanently suturing the prolapsed gland back down below the eyelid. If your dog has surgery to replace the tear gland and it re-prolapses, your vet may recommend removing the affected gland.
In some cases, surgery may be required to remove the whole eye, a procedure known as enucleation, which is recommended in dogs with large, aggressive, or invasive tumors causing irreversible damage to the dog's eye.

Does the Bump Disappear Naturally?
The lump on a dog's eyelid can last anywhere from a few days to several months, depending on the type. Some lumps are fast-growing and require prompt removal.
Eyelid growths with self-resolving tendencies can disappear within weeks to a few months. In some cases, the lump on a dog's eyelid may resolve naturally without any treatment.
Eyelid bumps and lumps caused by the papillomavirus, also known as warts, tend to vanish independently, especially in young dogs with robust immune systems. This is a common occurrence.
Histiocytoma, a type of tumor, can grow quickly before shrinking and resolving itself within a few weeks or months.
