Why Does My Dog Have Runny Eyes?

Understanding Canine Eye Discharge

Those watery eyes gazing up at you might be more than just an expression of love. Runny eyes in dogs, medically known as epiphora, can range from a minor irritation to a sign of something more serious. While some clear discharge is normal – much like how humans get “sleep” in their eyes – persistent or colored discharge warrants attention.

The eyes are windows to your dog’s health, and their condition can reveal much about potential underlying issues. A small amount of clear discharge that dries to a crust is typically nothing to worry about. However, when the discharge becomes excessive, changes color to yellow or green, or is accompanied by other symptoms, it’s time to investigate further.

Common Causes of Watery Eyes in Dogs

Several factors could be contributing to your dog’s runny eyes:

Allergies are among the most frequent culprits, causing clear, watery discharge similar to human hay fever. Seasonal allergens like pollen or year-round irritants such as dust mites can trigger this reaction. You might notice your dog rubbing their face more frequently during allergy flare-ups.

Blocked tear ducts, particularly in small breeds, prevent normal tear drainage, leading to overflow. This often results in reddish-brown staining beneath the eyes, especially noticeable in light-colored dogs. The discharge is typically clear but constant.

Eye infections (conjunctivitis) usually produce thicker, yellow or green discharge that may crust around the eyes. Bacterial infections often require antibiotic treatment, while viral infections might need supportive care until they run their course.

When to Seek Veterinary Care

While occasional clear discharge may not be concerning, certain signs indicate it’s time to visit your veterinarian:

• Thick, yellow or green discharge
• Redness or swelling around the eyes
• Squinting or excessive blinking
• Cloudiness or change in eye appearance
• Pawing at the eyes or rubbing the face
• Discharge accompanied by other symptoms like sneezing or lethargy

Prompt attention is crucial as some eye conditions can worsen rapidly. Corneal ulcers, for instance, are extremely painful and can lead to vision loss if untreated. Glaucoma, though less common, is an emergency requiring immediate care to preserve eyesight.

Prevention and Home Care

For mild cases, these measures may help:

• Gently wipe away discharge with a soft, damp cloth (use separate areas for each eye)
• Keep facial hair trimmed to prevent irritation
• Use veterinarian-approved eye washes
• Reduce exposure to known allergens when possible
• Ensure your dog’s living area is free from dust and irritants

Remember that home care should never replace professional veterinary advice when symptoms persist or worsen. Your dog’s vision is precious, and those watery eyes deserve proper attention to keep them bright, clear, and full of life.
