What are the signs that a dog’s eye ulcer is healing?

correct answerThe Short Answer is:

A significant reduction in corneal opacity and staining normally occurs within 3-4 days of the neovascularization process. The ulcer might also be healing if your dog is experiencing less pain less tearing or less squinting or if their overall symptoms have improved.

In this research you will know the answer to the query “What are the signs that a dog’s eye ulcer is healing?“.

You may be concerned if you see something wrong with your dogs eye but do not worry.

A number of causes contribute to eye ulcers in dogs.

What causes eye ulcers?

Usually eye ulcers are caused by trauma.

Make sure your dog is not too close to the ground.

Take a look at how fast it runs through the bushes and tall grasses chasing who knows what.

Yes its probably having a blast but its probably running into sticks leaves seeds etc.

Some of that stuff gets stuck in its eye and it scratches its eye.

Watch how dogs play together.

You think its a little rough at times do not you?

Cat scratch could explain this.

It might have rubbed its face on the carpet.

Face Planting into the couchs side could cause this.

The point is dogs are prone to eye ulcers because of their reckless abandon – one of the reasons we love them.

Other possibilities include a chemical burn such as from drywall dust or shampoo. 

It is possible that the eyelashes – yes eyelashes – may cause a problem.

The eyelashes rub against the eye due to entropion a birth defect that causes the eyelids to roll inward.

In the same way eyelashes can grow from the margin of the eyelid in a condition known as distichiasis.

When ectopic cilia grow abnormally from the underside of the eyelids they are called ectopic cilia. Sounds uncomfortable does not it? 

A genetic condition affecting fat metabolism epithelial dystrophy is also a less common cause.

It is more common in certain breeds of dogs such as boxers pugs Boston terriers and shih tzus.

There are also some dogs that may be genetically predisposed to “dry eye” – keratoconjunctivitis sicca – although this can also be caused by environmental factors.

A couple of other factors could be endocrine diseases such as diabetes Cushings syndrome or hypothyroidism. 

What are the different types of ulcers a dog can get on their eye?

It is possible for dogs to get two types of eye ulcers. These are indolent and corneal.

In order to understand what causes each ulcer we need to look at the cornea or the outermost layer of the eye.

The structure consists of three layers:

  • There is a very thin layer of cells called the epithelium.
  • Underneath the epithelium is the corneas support tissue the stroma.
  • Defending the body from injury and infection is the Descemets membrane.

The most common type of ulcer is an indolent ulcer which occurs when the epithelium and stroma fail to stick together.

Chronic inflammation of the corneal epithelium is sometimes referred to as spontaneous chronic corneal epithelial defects (SCCEDs) persistent corneal erosions or Boxer ulcers.

The condition occurs spontaneously in dogs of middle age and older and is more common in certain breeds.

Trauma such as a physical injury infection or disease can cause corneal ulcers which are also known as corneal erosions or corneal abrasions.

The epithelium may only be affected in mild cases but the stroma may be affected in severe cases. 

A descemetocele which affects the Descemets membrane is the most severe type of eye ulcer.

It is possible that irreparable damage could result if this membrane ruptures.

What are the symptoms of an eye ulcer in dogs?

Theres no doubt about it: these things are painful.

The following are some symptoms:

  • Blinking and/or squeezing its eye
  • By rubbing its eye with its paw or on the carpet or ground. 
  • An eye discharge.
  • Inflamed bloodshot or red eyes.
  • The eyes appear cloudy.
  • Injury to the eye surface that looks like a hole or crater.
  • Avoid bright lights.

Will a corneal ulcer need to be treated by a vet or will dog eye ulcer heal on its own?

Your options need to be carefully considered if your dog shows any of the above symptoms. He is in danger of losing his sight.

You should always have your dogs eye checked by a vet unless you’re certain that the injury is minor. Think about all the things a veterinarian can do that we cannot. A veterinarian is an expert.

They can:

  • To determine the dogs ability to judge distance light sensitivity and movement from a distance observe it from a distance.
  • Make sure the eyelids do not have entropion distichiasis or ectopic cilia.
  • Look for masses and abscesses.
  • Perform the Schirmer tear test (dry eye test) to determine if the eye produces enough tears.
  • Fluorescein staining should be done. Veterinarians do this by injecting a yellow-green dye into the eye to see where it collects. If the cornea is intact the dye will run off but if it is ulcerated it will stick.
  • Measure the pressure inside the eye with an ocular tonometer.
  • Adnexal exam (examination of the eyes accessory structures i.e. anything outside the eyeball).

Although I do not know about you I would do a poor job even pretending to do any of these things. In other words unless you’re sure your dogs eye injury is minor or already recovering rapidly you might want to consult a veterinarian.

How do I know if a corneal ulcer is healing? What are the signs that a dog’s eye ulcer is healing?

It is healing if your dog has a small crater-looking thing in its eye and it gets smaller each day and you know the cause.

However you should exercise caution. Eye infections can quickly worsen if you do not take action. An indolent dog eye ulcer would not heal by itself.

One indication of healing is neovascularization a process that occurs when blood vessels grow in the eye. When you see red blood vessels forming in the white part of your dogs eye near the ulcer you know its happening. These blood vessels are being created by your dogs eye to help the eye heal. The downside is that these blood vessels can remain for a long time and interfere with your dogs vision. Special eye drops can be prescribed by a veterinarian to help minimize their size and promote healing.

A fluorescein stain test is the only other way to determine the healing status of a corneal ulcer in a dog.

How long does it take for a corneal ulcer to heal?

As with humans dogs’ eyes have some of the fastest healing tissues in their bodies. It should take 3-5 days for a corneal ulcer that is not aggravated by another condition to heal. 

There are times when a veterinarian will have to treat eye ulcers in dogs. 

How will a vet treat an eye ulcer in a dog and what medication will they use?

Veterinarians have a variety of options after diagnosing an ulcer and assessing its underlying cause including:

  • Antibiotics can be administered orally or via eye drops. 
  • Medications to treat pain such as atropine or anti-inflammatories.
  • Protection of exposed nerve endings in the eye with contact lens-style bandages.
  • Eyedrops for lubrication.
  • Dogs cannot paw at their faces or rub their faces against things if they wear a buster collar.
  • Surgical procedures.

It is sometimes performed by a veterinary surgeon but it may also be done by a specialist known as a veterinary ophthalmologist.

It may be necessary for the surgeon to perform a keratotomy or debridement to remove the ulcerated epithelial cells. Then there is grid keratotomy which involves making small incisions in a cross-hatched pattern across an ulcer and in healthy areas to promote healing. 

The dogs eye may be surgically removed in the worst-case scenario. But since dogs are dogs they tend to recover and adapt quite well.

How much could treatment cost?

It could cost between $200 and $2000 depending on the size of the ulcer the type of anesthetic used the type of surgery the follow-up treatment etc.

However be assured that many of these eye surgeries are quite routine non-invasive and therefore quite inexpensive!


It is possible for your dog to develop eye ulcers just because it is old. Some dogs are genetically predisposed to developing eye ulcers. This could be due to the fact that they like to play rough with other dogs.

In any case they’re not uncommon. Our veterinarians have a lot of knowledge about them. Your dog would not panic either if you do not.
