Have you noticed your dog squinting, rubbing their eye, or acting unusually sensitive to light? These could be signs of glaucoma, a serious eye condition that can lead to pain and vision loss if left untreated. As a concerned pet owner, understanding this condition and knowing when to seek help can make all the difference for your furry friend.

⚠️ What to Watch For

Glaucoma in dogs is often subtle in its early stages, but catching it early can help preserve your dog’s vision and prevent discomfort. Here are some common signs to look out for:

  • Redness in the eye (bloodshot appearance)
  • Cloudy or bluish appearance of the cornea
  • Frequent squinting or blinking
  • Swollen or bulging eye
  • Excessive tearing or discharge
  • Reluctance to be touched around the head or face
  • Visible vision problems, such as bumping into objects

If you notice any of these symptoms, it’s important to act quickly. Glaucoma can progress rapidly, causing irreversible damage to your dog’s eyes.

🔍 Possible Causes

Glaucoma occurs when the fluid inside the eye, called aqueous humor, doesn’t drain properly. This buildup increases intraocular pressure, which can damage the optic nerve. There are two main types of glaucoma in dogs:

  • Primary Glaucoma: This is often hereditary and more common in certain breeds like Cocker Spaniels, Poodles, and Siberian Huskies.
  • Secondary Glaucoma: This occurs as a result of another eye condition, such as inflammation, trauma, or a tumor blocking fluid drainage.

Some dogs are genetically predisposed to developing glaucoma, while others may experience it due to underlying health issues. Regular vet check-ups are essential for identifying risk factors early.

✅ What You Can Do at Home

While glaucoma requires veterinary diagnosis and treatment, there are steps you can take at home to support your dog’s eye health:

  • Monitor your dog’s eyes regularly for any signs of redness, cloudiness, or discomfort.
  • Keep your dog’s environment safe to prevent eye injuries. Remove sharp objects and avoid rough play that could harm their eyes.
  • Provide a healthy diet with nutrients like omega-3 fatty acids, which support overall eye health. Consult your vet for dietary recommendations.
  • Protect your dog’s eyes from harsh sunlight by limiting exposure or using dog-friendly goggles if needed.

Remember, these steps are supportive measures and not a substitute for veterinary care. If you suspect glaucoma, don’t delay seeking professional advice.

💡 When to Call a Vet

Glaucoma is a medical emergency that requires immediate veterinary attention. If your dog shows any of the following signs, contact your vet or a pet telehealth service like Dial A Vet right away:

  • Sudden onset of symptoms like redness, swelling, or cloudiness
  • Severe pain (e.g., whining, pawing at the eye, or avoiding light)
  • Rapid loss of vision or difficulty navigating their surroundings

Your vet will likely perform tests to measure your dog’s intraocular pressure and determine the best treatment plan. This may include medications to reduce pressure, surgery to improve fluid drainage, or other interventions depending on the severity of the condition.

According to VCA Animal Hospitals, early intervention is key to managing glaucoma and preventing further complications (source).
