Red eyes in pets can be alarming, and there are several reasons why your pet may be experiencing this symptom. While red eyes can sometimes result from minor irritations, they can also indicate more serious underlying health issues. Here are some common causes of red eyes in pets and when to seek veterinary care.
Allergies
Allergies can cause red, itchy eyes in pets, often due to environmental factors like pollen, dust, or food. These irritants trigger inflammation, leading to discomfort and eye redness.
Symptoms of Allergies in Pets
- Red, watery eyes
- Frequent pawing or rubbing at the eyes
- Sneezing or scratching
- Swelling around the eyes
Tip
If you suspect your pet has allergies, keep them away from known irritants and consult your vet about possible antihistamine treatments.
Conjunctivitis (Pink Eye)
Conjunctivitis, commonly known as pink eye, occurs when the tissue lining the eyelid becomes inflamed. It’s typically caused by an infection, irritant, or allergies and is one of the most frequent reasons for red eyes in pets.
Symptoms of Conjunctivitis in Pets
- Redness and swelling of the eyes
- Eye discharge (clear, yellow, or green)
- Squinting or excessive blinking
- Sensitivity to light
Tip
Use a clean, damp cloth to gently wipe away any discharge, but avoid touching the eye directly. Always visit your vet for proper diagnosis and treatment.
Keratoconjunctivitis Sicca (Dry Eye)
Dry eye is a condition where your pet’s eyes don’t produce enough tears to stay lubricated, leading to irritation and redness. This can become a chronic condition if not treated.
Symptoms of Dry Eye in Pets
- Thick, mucus-like discharge
- Red or inflamed eyes
- Frequent blinking or squinting
- Pawing at the eyes
Tip
Use artificial tear drops (approved by your vet) to help lubricate the eyes until you can get veterinary care. Long-term treatment may involve prescription eye drops.
Glaucoma
Glaucoma occurs when the pressure inside your pet’s eye increases, which can lead to pain, redness, and eventually blindness if left untreated. This is a serious condition requiring immediate attention.
Symptoms of Glaucoma in Pets
- Redness in the whites of the eye
- Cloudy appearance of the eye
- Swelling or bulging of the eye
- Signs of pain, such as pawing at the face or avoiding light
Tip
Glaucoma is a medical emergency. Contact your vet immediately if your pet shows these symptoms to prevent permanent damage.
Injury or Foreign Object
Pets with sudden red eyes, squinting, or tearing may have an injury or foreign object lodged in the eye, such as dirt or grass. This requires immediate veterinary attention to avoid further damage.
Symptoms of Eye Injury in Pets
- Sudden redness
- Excessive tearing or squinting
- Rubbing or pawing at the eye
- Sensitivity to touch
Tip
Do not attempt to remove any foreign objects yourself. Keep your pet calm and contact your vet for safe removal and treatment.
Infections
Bacterial, viral, or fungal infections can cause red, inflamed eyes, often accompanied by discharge. Infections may stem from other health issues, such as upper respiratory infections or exposure to infected animals.
Symptoms of Eye Infections in Pets
- Redness and swelling
- Yellow or green discharge
- Squinting or sensitivity to light
- Possible fever or lethargy
Tip
Keep your pet away from other animals to prevent spreading infection. Wipe away discharge gently, but seek veterinary care for proper antibiotics or antiviral treatment.
Corneal Ulcers
Corneal ulcers are painful open sores on the surface of the eye, usually caused by trauma, infection, or foreign objects. Immediate treatment is necessary to avoid long-term damage.
Symptoms of Corneal Ulcers in Pets
- Red, inflamed eyes
- Excessive blinking or tearing
- Cloudy or discolored appearance of the eye
- Visible sores or ulcers on the eye’s surface
Tip
If you suspect a corneal ulcer, keep your pet from rubbing or pawing at the eye, and seek urgent veterinary care to prevent further damage.
When To See a Vet
If your pet’s red eyes are accompanied by swelling, discharge, squinting, or signs of pain, it’s crucial to consult a veterinarian promptly. Early diagnosis and treatment can prevent complications and help your pet recover more quickly.
