Your dog’s eyes are a window to their health, and red eyes can be a sign of something serious. If you notice your dog’s eyes are red, it’s important to understand the possible causes and seek veterinary attention if necessary.
This article will delve into the various reasons why your dog might have red eyes, from common irritations to more serious conditions. We’ll explore the symptoms, potential causes, and when to see a veterinarian.
Common Causes of Red Eyes in Dogs
Red eyes in dogs can be caused by a variety of factors, ranging from mild irritations to serious infections.
Conjunctivitis
Conjunctivitis, also known as pink eye, is a common eye infection that affects the conjunctiva, the clear membrane that lines the inside of the eyelids and covers the white part of the eye. It can be caused by bacteria, viruses, allergies, or irritants.
Symptoms of Conjunctivitis:
- Redness of the eye
- Discharge from the eye (clear, white, yellow, or green)
- Itching
- Squinting
- Sensitivity to light
Dry Eye
Keratoconjunctivitis sicca, or dry eye, is a condition where the tear glands don’t produce enough tears to keep the eye lubricated. This can cause inflammation, redness, and pain.
Symptoms of Dry Eye:
- Redness
- Excessive blinking
- Eye discharge
- Clouding of the cornea (the clear front part of the eye)
Corneal Ulcers
Corneal ulcers are open sores on the cornea. They can be caused by injuries, infections, or dry eye.
Symptoms of Corneal Ulcers:
- Redness
- Pain
- Squinting
- Excessive tearing
- Cloudiness of the cornea
Allergies
Allergies can cause red, itchy eyes in dogs.
Symptoms of Allergies:
- Redness
- Itching
- Discharge
- Sneezing
- Runny nose
Foreign Objects
A speck of dust, grass, or other debris can get trapped in your dog’s eye, causing irritation and redness.
Symptoms of Foreign Objects:
- Redness
- Pain
- Excessive blinking
- Pawing at the eye
- Discharge
Glaucoma
Glaucoma is a condition that occurs when the fluid pressure inside the eye builds up, damaging the optic nerve. This can lead to blindness if left untreated.
Symptoms of Glaucoma:
- Redness
- Pain
- Cloudy cornea
- Dilated pupils
- Blindness (in severe cases)
When to See a Veterinarian
If your dog has red eyes, it’s important to contact your veterinarian. They can diagnose the underlying cause of the redness and recommend the appropriate treatment.
Here are some signs that you should see a vet immediately:
- Redness accompanied by pain or discomfort: Your dog is squinting, pawing at their eyes, or rubbing their face on furniture.
- Discharge: The discharge is thick, yellow, or green.
- Cloudiness of the cornea: The cornea appears cloudy or opaque.
- Pupil dilation: The pupil is dilated and doesn’t constrict in response to light.
- Sudden onset of redness: The redness appeared suddenly and you don’t know what caused it.
Treating Red Eyes in Dogs
The treatment for red eyes in dogs will depend on the underlying cause. Here are some common treatments:
- Antibiotics: For bacterial infections.
- Anti-inflammatory medications: To reduce inflammation.
- Artificial tears: To lubricate the eyes in cases of dry eye.
- Surgery: In some cases, surgery may be necessary to remove foreign objects or repair corneal ulcers.
- Glaucoma medications: To lower the pressure inside the eye.
How to Prevent Red Eyes in Dogs
While not all red eyes can be prevented, there are some things you can do to reduce the risk:
- Keep your dog’s environment clean: Regularly clean your dog’s bedding and toys to reduce allergens.
- Avoid using harsh chemicals or sprays: These can irritate your dog’s eyes.
- Provide fresh water: Dehydration can lead to dry eye.
- Don’t let your dog rub their eyes: This can further irritate the eyes and make the condition worse.

Red eyes in dogs can be caused by a variety of factors, ranging from mild irritations to serious conditions. If you notice your dog’s eyes are red, it’s important to contact your veterinarian to get a diagnosis and appropriate treatment.
