Why are my dogs eyes red?
Updated: June 29, 2024Introduction to Canine Eye Redness
When you notice that your dog's eyes are red, it can be quite alarming. Redness in your dog's eyes can stem from a variety of causes, ranging from minor irritations to more serious health concerns. Understanding the potential reasons behind this symptom and knowing when to seek veterinary care is essential for every dog owner.
Common Causes of Red Eyes in Dogs
Allergies
Just like humans, dogs can suffer from allergies. These can be environmental, such as pollen, dust mites, or mold, or they can be food-related. Allergies can cause a dog’s eyes to become red, itchy, and watery. Often, you might also notice other symptoms such as sneezing, nasal discharge, or excessive scratching.
Conjunctivitis (Pink Eye)
Conjunctivitis, also known as pink eye, is an inflammation of the conjunctiva, the tissue lining the eyelids and the white part of the eye. This condition can be caused by bacteria, viruses, allergens, or irritants such as smoke or shampoo. Symptoms include redness, discharge, and swelling around the eyes.
Dry Eye (Keratoconjunctivitis Sicca)
Dry eye occurs when a dog's eyes do not produce enough tears, leading to dryness and inflammation. This condition can cause redness, excessive blinking, and a thick, yellowish discharge. If left untreated, dry eye can result in corneal ulcers and vision loss.
Glaucoma
Glaucoma is a serious condition caused by increased pressure within the eye. This can lead to redness, swelling, pain, and vision loss. Glaucoma requires immediate veterinary attention, as it can rapidly progress and cause permanent damage to the eye.
Injuries and Trauma
Dogs are curious creatures and can easily injure their eyes while exploring their environment. Scratches, foreign objects, or blunt trauma can lead to red, irritated eyes. If you suspect that your dog’s red eye is due to an injury, it is essential to seek veterinary care promptly.
Less Common Causes of Red Eyes in Dogs
Uveitis
Uveitis is the inflammation of the uvea, the middle layer of the eye. This condition can be caused by infections, immune-mediated diseases, or trauma. Symptoms include redness, squinting, and light sensitivity. Uveitis can lead to complications such as glaucoma if not treated promptly.
Corneal Ulcers
Corneal ulcers are open sores on the cornea, the clear outer layer of the eye. These ulcers can result from injuries, infections, or chronic dry eye. Symptoms include redness, excessive tearing, squinting, and pawing at the eye. Corneal ulcers require prompt veterinary care to prevent complications and promote healing.
Eyelid Abnormalities
Certain breeds are prone to eyelid abnormalities such as entropion (inward rolling of the eyelid) or ectropion (outward rolling of the eyelid). These conditions can cause irritation, redness, and discomfort. Surgical correction may be necessary to alleviate the symptoms and prevent further complications.
Systemic Diseases
Some systemic diseases, such as hypertension, diabetes, or autoimmune disorders, can manifest with ocular symptoms, including red eyes. These conditions often require a comprehensive veterinary examination and appropriate treatment to manage both the ocular and systemic issues.
Diagnosing the Cause of Red Eyes
Veterinary Examination
A thorough veterinary examination is crucial to determine the underlying cause of your dog's red eyes. The veterinarian will conduct a physical examination, review your dog's medical history, and inquire about any additional symptoms or recent changes in behavior or environment.
Diagnostic Tests
Depending on the preliminary findings, the veterinarian may recommend diagnostic tests such as:
- Schirmer tear test: Measures tear production to diagnose dry eye.
- Fluorescein stain test: Detects corneal ulcers or scratches.
- Tonometer test: Measures intraocular pressure to diagnose glaucoma.
- Cytology or culture: Identifies bacterial or viral infections.
- Blood tests: Evaluates for systemic diseases that may affect the eyes.
Treatment Options for Red Eyes in Dogs
Medical Management
Treatment for red eyes in dogs will depend on the underlying cause. Common medical management options include:
- Antibiotic or anti-inflammatory eye drops/ointments.
- Allergy medications or hypoallergenic diets.
- Artificial tear supplements for dry eye.
- Medications to reduce intraocular pressure in cases of glaucoma.
Surgical Intervention
In some cases, surgical intervention may be necessary to address the underlying cause of red eyes. Examples include:
- Removal of foreign objects or repair of injuries.
- Surgical correction of eyelid abnormalities.
- Surgical procedures to alleviate intraocular pressure in severe glaucoma cases.
Preventing Red Eyes in Dogs
Regular Veterinary Check-ups
Routine veterinary check-ups are essential for maintaining your dog's overall health and early detection of potential eye problems. Regular eye examinations can help identify issues before they become severe.
Environmental Management
Minimizing your dog's exposure to potential allergens or irritants can help prevent red eyes. Keep your home clean and free of dust, mold, and smoke. Use pet-safe cleaning products and grooming supplies.
Proper Eye Care
Maintaining good eye hygiene can help prevent infections and irritations. Gently clean your dog's eyes with a damp cloth to remove discharge and debris. Avoid using human eye drops or medications without veterinary guidance.
When to Seek Veterinary Care
It's important to know when to seek veterinary care for your dog's red eyes. Immediate veterinary attention is necessary if you notice any of the following:
- Severe redness, swelling, or discharge.
- Squinting or excessive blinking.
- Pawing at the eyes or signs of pain.
- Changes in vision or behavior.
- Symptoms that persist or worsen despite home care.
Understanding the various causes of red eyes in dogs and the importance of timely veterinary care can help you ensure your furry friend's eye health. By staying informed and proactive, you can make the best decisions for your dog's well-being.

Dogs have a unique vision system that differs significantly from that of humans. While humans have trichromatic vision, meaning we can perceive a wide range of colors through the combination of three types of cone cells in our retinas, dogs have dichromatic vision. This means they have only two types of cone cells, which limits their color perception.
