Key points

  • Dog eye allergies cause red, watery, itchy eyes.

  • Diagnosis is by history, physical exam, eliminating other conditions and testing for allergies.

  • Treatment is with eye drops for simple cases, or by mouth in more generalized allergies.

  • Treatment may be life-long, especially if the allergen(s) cannot be completely avoided.

Symptoms & types

Dog eye allergies can be caused by allergies to food, pollen, dust mites, cigarette smoke, perfumes, or household cleaning products.

Understanding the diagnostics

Learning about the causes

If your veterinarian gives you instructions for a diet trial, follow them to the letter! Don’t be tempted to think the odd treat won’t hurt, it will invalidate the diet trial and take longer to get to the bottom of your dog’s allergies.

Best treatment options

Home remedies and their effectiveness

Home remedies may temporarily improve symptoms but wouldn’t provide an effective long-term solution. It’s best to leave the treatment to your veterinarian.
