Dog Eye Problems: Common Conditions, Warning Signs and Safe Daily Care
Your dog’s eyes say a lot about how they feel. Watery, red or cloudy eyes can be a small irritation or the start of something serious.
This guide covers the most common dog eye problems, the signs to watch, the emergency red flags, and simple daily habits that support eye hygiene.
Quick answer: Dog eye problems range from mild irritation to sight-threatening emergencies. Redness, discharge, squinting and cloudiness are the main warning signs. Squinting, a cloudy eye or a bulging eye means see a veterinarian the same day. For everyday care, gently wipe discharge and keep the eye area clean with a product formulated to support daily eye hygiene.
Daily eye care, made simple
A gentle rinse can be part of your dog’s routine. It is formulated to support daily eye hygiene and helps gently cleanse the eye area.
What counts as a dog eye problem?
A dog’s eye has several layers. The clear cornea sits at the front. Behind it are the iris, lens and retina. The nictitating membrane, often called the third eyelid, sweeps across the surface to protect it.
A problem in any layer can change how the eye looks or feels. That is why a red eye and a cloudy eye are not the same thing, even if both look “off” to you.
Dogs hide pain well. Subtle signs matter, and the sections below show what to look for. You can also read our guides on dog eye discharge and dog eye infections for deeper detail.
Common signs of eye trouble
Watch for these changes:
- Discharge that is clear, yellow, green or crusty
- Redness in the white of the eye or inner lids
- Squinting or holding one eye shut
- Pawing or rubbing the face on carpet
- Cloudiness or a bluish haze
- A bulging eye, uneven pupils or light sensitivity
- Bumping into furniture, especially in dim light
One sign alone may be minor. Several together, or any sudden change, call for an exam.
The most common dog eye problems
Conjunctivitis (pink eye)
Inflammation of the pink tissue lining the eyelids. Causes include allergies, irritants and infection. See our dog pink eye guide.
Epiphora and tear staining
Epiphora means tears overflow onto the face. Over time this leaves rust-colored streaks. Read more in tear stains on dogs.
Cherry eye
The gland of the third eyelid pops out and looks like a red lump. It is most common in young dogs of some breeds. See cherry eye in dogs.
Corneal ulcer
A scratch or sore on the cornea. It is painful and can worsen fast. Learn more about a dog eye ulcer.
Dry eye (KCS)
Keratoconjunctivitis sicca happens when the eye does not make enough tears. Thick mucus and dull-looking eyes are typical.
Glaucoma, cataracts, entropion and uveitis
Glaucoma is high pressure inside the eye and is painful. Cataracts make the lens cloudy. Entropion rolls the eyelid inward so lashes rub the cornea, while ectropion lets the lid sag. Uveitis is inflammation inside the eye. All need a veterinary exam.
What causes dog eye problems?
- Anatomy: flat-faced (brachycephalic) breeds like pugs, Boston terriers, shih tzus and bulldogs have prominent eyes and shallow sockets.
- Injury: scratches from play, brush, cat claws or debris.
- Allergies: pollen, dust and mold can irritate the eyes seasonally.
- Hair and lashes: long facial hair or extra lashes rub the surface.
- Genetics and age: cataracts, dry eye and glaucoma can run in families, and older dogs are more prone.
- Other health issues: immune conditions and diabetes can affect the eyes.
Emergency red flags: see a vet the same day
Do not wait if you notice any of these:
- Eye held shut or intense squinting
- Cloudy, blue-gray or suddenly white eye
- Bulging, swollen or very red eye
- Visible injury, blood or an object in the eye
- Sudden vision loss or disorientation
- Different-sized pupils
Glaucoma and deep ulcers can cause permanent damage within hours. When in doubt, call your veterinarian or an emergency clinic.
How veterinarians check the eyes
Your vet will start with a close look and a light. Common tests include:
- Schirmer tear test: a thin paper strip measures tear production.
- Fluorescein stain: a dye that glows on the cornea if there is an ulcer or scratch.
- Tonometry: a quick reading of eye pressure to screen for glaucoma.
- Ophthalmoscopy: a look at the retina and lens.
The American College of Veterinary Ophthalmologists lists common conditions and when to ask for a specialist referral.
Safe at-home eye hygiene
Daily hygiene will not replace an exam, but it can keep the eye area comfortable between visits.
- Wash your hands first.
- Wipe discharge from the corner outward with a clean, soft, damp cloth or sterile gauze. Use a fresh piece for each eye.
- Trim hair around the eyes with blunt-tipped scissors, or ask your groomer.
- Rinse the eye area with a gentle, dog-appropriate eye rinse formulated for the purpose.
- Keep faces dry. Moisture in folds invites irritation.
- Do not rub, pick at crusts or use human drops or old leftover medication.
If the eye looks worse after cleaning, stop and call your veterinarian.
Ingredients you may see in eye care products
Labels can be confusing. Here is what common ingredients are generally used for:
- Sterile saline: a salt-water solution that is gentle on the eye surface and used to flush away dust and debris.
- Hypochlorous acid: a mild cleansing ingredient found in some eye-area cleaners.
- Chamomile-type botanicals: sometimes included for a soothing feel, though quality and sensitivities vary.
- Hyaluronic acid: a moisture-binding ingredient used in some lubricating formulas.
Look for products made for dogs, avoid anything with alcohol or fragrance, and always check the full ingredient list. For the Pure Majesty rinse, see the product page for the full ingredient list.
How to help prevent eye problems
- Keep up with annual wellness exams, which include a quick eye check.
- Clean the eye area daily, especially in flat-faced breeds.
- Keep hair trimmed and avoid shampoo near the eyes.
- Do not let dogs hang their heads out of car windows.
- Keep nails short to reduce accidental scratches.
- Ask your vet about breed-specific risks.

Frequently Asked Questions
What are the most common dog eye problems?
The most common are conjunctivitis, tear staining (epiphora), cherry eye, corneal ulcers, dry eye (keratoconjunctivitis sicca), cataracts, glaucoma, entropion and uveitis. Some are mild. Others can threaten sight within hours, so any sudden change deserves a call to your veterinarian.
How do I know if my dog’s eye problem is an emergency?
Heavy squinting, a cloudy or bluish eye, a bulging or very red eye, a visible injury, or sudden pain and pawing all warrant a same-day visit. Glaucoma and deep corneal ulcers can cause lasting damage quickly.
Can I use human eye drops on my dog?
No. Many human drops contain ingredients that are not suitable for dogs, and some can make an ulcer or glaucoma worse. Only use drops your veterinarian has recommended for your dog’s exact condition.
Why does my pug or shih tzu always have watery eyes?
Flat-faced (brachycephalic) breeds have shallow eye sockets, prominent eyes and facial folds, which affect how tears drain and how well the eyelids protect the eye. Daily gentle cleaning of the eye area helps keep it comfortable, and regular vet checks catch problems early.
Does the Pure Majesty Eye Cleansing Rinse replace veterinary care?
No. It is formulated to support daily eye hygiene and helps gently cleanse the eye area. It is not a substitute for an exam, and it should not be used to manage pain, cloudiness or ongoing discharge without veterinary advice.
Support your dog’s eye comfort every day
Keep the eye area clean and comfortable. Ask your veterinarian about any lasting changes.
