Entropion surgery in dogs is a procedure that corrects an inward-rolling eyelid, stopping the fur and lashes from rubbing against the surface of the eye. It’s one of the most common eyelid surgeries in veterinary medicine, and the most widely used technique involves removing a small crescent of skin just below (or above) the affected eyelid to pull it back into its normal position. The surgery is straightforward in most cases, with a success rate that keeps roughly 88 to 92% of dogs from needing a second procedure.
Why Dogs Need Entropion Surgery
Entropion happens when part of a dog’s eyelid folds inward, pressing hair and lashes directly against the cornea. This creates constant friction that irritates the eye and, over time, can cause serious damage. Most dogs with entropion will squint, hold the affected eye shut, and tear excessively. Some develop a thick, mucus-like discharge. In severe or long-standing cases, the ongoing irritation triggers blood vessels and dark pigment to grow across the cornea, which can permanently impair vision.
The condition is primarily hereditary, linked to the shape of a dog’s skull, eye sockets, and skin folds. Shar-Peis are by far the most affected breed, with about 15% developing entropion. Chow Chows (around 9%), Neapolitan Mastiffs (nearly 7%), Clumber Spaniels (6%), Saint Bernards (5%), and English Bulldogs (close to 5%) also have notably high rates. Flat-faced breeds sometimes have entropion in the inner corner of the eye near the nose and, interestingly, may show no obvious signs of discomfort despite the eyelid rolling inward.
Entropion can also develop secondarily. A painful corneal ulcer can cause the eyelid muscles to spasm and turn the lid inward, and scarring from an injury or chronic inflammation can pull the eyelid out of position. Before recommending surgery, veterinarians distinguish between these types. Applying a numbing drop to the eye can help: if the eyelid returns to its normal position once pain is removed, the entropion is spastic (caused by pain) rather than structural. Spastic entropion may resolve once the underlying problem, like an ulcer, is treated. Structural entropion requires surgical correction.
How the Surgery Works
The standard technique is called the Hotz-Celsus procedure. The surgeon marks a crescent-shaped section of skin just outside the eyelid margin, removes it, then sutures the wound closed. As the skin heals and tightens, it pulls the eyelid edge outward into its correct position so the lashes no longer contact the eye. The amount of skin removed is carefully judged to avoid overcorrection, which would cause the eyelid to roll outward instead.
In a UK study of over 200 surgical entropion cases, the Hotz-Celsus technique was used in about 40% of eyes, stay sutures (temporary stitches that evert the lid) in another 38%, and wedge resection, where a small section of the eyelid itself is removed to shorten it, in about 13%. Some dogs, particularly breeds with excessive facial skin or multiple eyelid issues, need a combination of these techniques. A surgeon might pair the Hotz-Celsus with a wedge resection to address both the rolling and the excess eyelid length in one procedure. Complex cases involving multiple parts of the eyelid or both eyes often benefit from a veterinary ophthalmologist rather than a general practitioner.
The procedure is performed under general anesthesia. It typically takes 30 to 60 minutes depending on whether one or both eyes are involved and how many eyelid sections need correction.
Puppies and Eyelid Tacking
Puppies under about 12 weeks old often aren’t candidates for permanent surgery because their skulls and facial skin are still growing. A puppy with heavy skin folds may grow into a more normal eyelid position as its head matures. For these young dogs, veterinarians use a temporary procedure called eyelid tacking. Small stitches or surgical staples are placed to roll the eyelid outward, protecting the cornea while the puppy develops.
In a study tracking juvenile dogs with entropion, the condition resolved without permanent surgery in about 37% of eyes, meaning those dogs grew out of it after tacking alone. For the rest, permanent correction was eventually needed. Importantly, when juvenile dogs do require surgery, their long-term outcomes are just as good as adult dogs. The recurrence rate after surgery was roughly 13% in juveniles compared to 8% in adults, a difference that was not statistically significant.
What Recovery Looks Like
Your dog will come home the same day in most cases. The surgical site takes 10 to 14 days to heal, and external sutures are removed at that point. During recovery, your dog needs to wear an Elizabethan collar (the cone) at all times to prevent scratching or rubbing at the stitches. This is non-negotiable: one good scratch can tear sutures and compromise the repair.
Activity should be limited for those 10 to 14 days. Keep your dog clean, dry, and warm, and check the incision daily during the first week for signs of swelling, redness, or discharge that could indicate infection. Most dogs go home with an oral anti-inflammatory pain medication. If a corneal ulcer was present before or during surgery, your vet may also prescribe antibiotic eye drops and pain-relieving eye drops to help the cornea heal alongside the eyelid.
Swelling around the surgical site is normal for the first few days and can actually make the eyelid look slightly overcorrected, with the lid edge pulling outward more than expected. This typically settles as the swelling resolves. The final cosmetic and functional result becomes clear a few weeks after surgery.
Risks and Possible Complications
The most common concern is undercorrection, where not enough skin is removed and the eyelid still rolls inward to some degree. This requires a revision surgery. Overcorrection is the opposite problem: too much skin is removed, causing the eyelid to sag outward (a condition called ectropion), which exposes the inner lining of the lid. Surgeons tend to err on the conservative side for this reason, preferring a minor undercorrection that can be revised over an overcorrection that’s harder to fix.
Other potential complications include bleeding, infection, wound separation, scarring, and in rare cases corneal injury during the procedure. Overall, outcomes are good for most dogs, but some do require a second surgery. Breeds with heavy facial skin folds, like Shar-Peis and Neapolitan Mastiffs, are more likely to need revisions or staged procedures because their anatomy creates multiple points of eyelid rolling that are difficult to fully address in a single operation.
Cost Considerations
Entropion surgery costs vary widely depending on your location, whether a general veterinarian or a board-certified ophthalmologist performs the procedure, and whether one or both eyes need correction. General practice fees tend to range from roughly $500 to $1,500 per eye, while specialist ophthalmologists may charge $1,000 to $3,000 or more per eye. Bilateral surgery (both eyes) is common in predisposed breeds and will be at the higher end of those ranges. Pre-surgical diagnostics, anesthesia, medications, and the follow-up suture removal appointment are sometimes included in a quoted price and sometimes billed separately, so it’s worth asking what the estimate covers.
For dogs that aren’t surgical candidates due to age, anesthesia risk, or cost constraints, ongoing medical management with lubricating eye drops and treating any secondary corneal damage can help protect the eye. This approach requires consistent, long-term commitment and doesn’t fix the underlying problem, but it can keep some dogs comfortable when surgery isn’t an option.
