Does Your Dog Have Uveitis?

If your dog’s eye looks red or cloudy, or they’re squinting like the light is bothering them, don’t wait to see if it passes. These are classic signs of uveitis, which is inflammation inside the eye. It’s painful, it can escalate quickly, and without treatment it can lead to permanent vision loss.

The good news: caught early and managed well, many dogs do recover, and most can be kept comfortable long-term. Here’s what you need to know.

What is uveitis and what causes it?

Uveitis is inflammation of the uvea, the inner vascular layer of the eye made up of the iris (the colored part), the ciliary body (which controls focus and fluid production), and the choroid (the layer behind the retina). It’s painful, and it’s as much a symptom as it is a diagnosis. Your vet will work to find the root cause rather than just treating the inflammation itself, because what’s driving it shapes how it’s treated.

Common causes include:

• Infections: Bacterial infections like Leptospirosis or Brucellosis, viral causes like canine distemper, fungal infections like Blastomycosis or Cryptococcus, and parasitic causes like Toxoplasma.
• Immune-mediated disease: The immune system mistakenly attacks the eye’s own tissue. This is more common in breeds like Golden Retrievers and Labrador Retrievers.
• Trauma: A scratch, blunt injury, or foreign object in or near the eye.
• Metabolic disease: Diabetes and high blood pressure are both known triggers.
• Cataracts: As the lens breaks down, it can leak proteins that provoke inflammation.
• Tumors: Cancers originating in the eye or spreading from elsewhere in the body.
• Idiopathic causes: In many cases, a cause is never found despite thorough testing.

What are the signs of uveitis in dogs?

Uveitis doesn’t always announce itself dramatically. Sometimes it starts subtly, which is exactly why it can progress before owners realize something’s wrong. Here’s what to watch for:

• Red eye: Bloodshot or deep pinkish-red, especially around the whites of the eye.
• Squinting or keeping the eye partially closed: A sign the eye is painful.
• Sensitivity to light: Your dog avoids bright rooms or sunlight.
• Cloudy or blue-gray eye: Caused by swelling of the clear front surface of the eye due to fluid buildup.
• Tearing or discharge: Watery or mucous-like fluid around the eye.
• A smaller-than-normal pupil: Inflammation can cause the pupil to constrict or appear irregular.
• Visible haziness inside the eye: The normally clear gel inside the eye may look murky.

If your dog’s eye looks sunken or soft, or they seem to have lost vision suddenly, get to a vet the same day. These can signal a serious complication like a severe pressure drop inside the eye, or secondary glaucoma, a dangerous spike in pressure that can cause permanent blindness within hours.

How do vets diagnose canine uveitis?

Your vet will start with a detailed eye exam, looking at the structures inside and around the eye using a slit lamp (a specialized magnifying light) and an ophthalmoscope (a tool to examine the back of the eye). One of the most important measurements they’ll take is intraocular pressure, the pressure inside the eye.

This matters a lot: uveitis typically causes low intraocular pressure, because the inflamed ciliary body produces less fluid. Glaucoma, on the other hand, causes high intraocular pressure. Getting this distinction right changes the treatment entirely, since what helps one condition can worsen the other.

Depending on what they find, your vet may also recommend blood work, urine tests, imaging like an eye ultrasound, or referral to a veterinary ophthalmologist (an eye specialist) to identify the underlying cause and rule out systemic disease.

How is uveitis in dogs treated?

Treatment has two goals: control the inflammation to protect vision, and address whatever’s driving it.

Your vet will likely prescribe one or more of the following:

• Prednisolone eye drops or ointment: A corticosteroid that reduces inflammation directly in the eye
• Flurbiprofen eye drops: A non-steroidal anti-inflammatory used alongside or instead of steroids, depending on the case
• Atropine eye drops: Dilates the pupil to relieve pain and prevent the iris from sticking to the lens (a complication called synechia)
• Oral anti-inflammatories or antibiotics: If infection or systemic disease is involved

If an underlying condition is identified, like diabetes, high blood pressure, or a fungal infection, treating that directly is just as important as the eye drops themselves.

Giving Eye Drops at Home and Monitoring for Flare-Ups

A lot of treatment success happens at home, between vet visits. Getting the eye drops right and knowing what to look for can make a real difference in your dog’s recovery.

How to give eye drops

1. Wash your hands before you start, every time.
2. Sit your dog on a stable surface or tuck them gently between your legs so they can’t back away.
3. Tilt their head back slightly and use one hand to gently pull down the lower lid to hold the eye open.
4. Hold the dropper about an inch above the eye. Never let the tip touch the eye or eyelid, since contact introduces bacteria.
5. Aim for the inner corner of the eye rather than directly onto the pupil.
6. If you’re using multiple drops or a combination of drops and ointment, wait at least five minutes between each one so they don’t wash each other out.
7. Finish with a treat or some praise every single time. Positive association makes the next round noticeably easier.

What to watch between appointments

Uveitis can flare up again, especially if the underlying cause isn’t fully resolved. Taking a quick photo of the eye each day is one of the most useful things you can do. It lets you and your vet track subtle changes that are easy to miss when you’re looking at the same dog every day. Beyond that, keep an eye on how red or cloudy the eye looks, whether your dog is squinting more than usual, any new or changing discharge, whether light seems to bother them, and any behavioral changes like bumping into things or reluctance to go outside.

If the eye looks cloudier, redder, or more painful between scheduled rechecks, call your vet. A flare-up caught early is a lot easier to manage than one that’s been developing for days.

Can dogs recover from uveitis

It depends on what’s causing it. Dogs with uveitis triggered by a treatable underlying condition, like a bacterial infection or cataracts removed surgically, often do very well. Dogs with chronic, immune-mediated uveitis may need long-term medication to keep flare-ups under control and prevent complications.

Left untreated or undertreated, uveitis can lead to cataracts, glaucoma, retinal detachment, or permanent vision loss. That’s not meant to alarm you. It’s just a good reason to stay consistent with treatment and not skip follow-up appointments, even when the eye looks like it’s improving.

Does pet insurance cover uveitis in dogs?

Yes, uveitis is eligible for coverage under a Lemonade Pet accident and illness policy, as long as the condition isn’t pre-existing. That means your dog shouldn’t be showing any signs or symptoms before your policy starts or during your waiting period.

Specialist ophthalmology visits, diagnostic bloodwork, and ongoing prescription eye drops can add up quickly, especially when treatment stretches over months. Getting coverage in place while your dog is healthy is what makes it actually useful when something like this comes up.

Before we go

Uveitis is painful and can move fast, but it’s also very treatable when it’s caught early. Stay consistent with the eye drops, keep up with follow-up appointments, and don’t wait to call your vet if something looks off between rechecks. Your dog is counting on you to notice, and the fact that you’re paying this close attention already makes a difference.
