How to clean gunk from your dog's eyes
Visit your vet.
If your dog has gunk or discharge draining from her eyes, you first need to make sure it's not a sign of a serious health problem. Make an appointment with your veterinarian to determine the cause of the discharge before addressing the problem on your own.
While you should evaluate your dog for symptoms, you should never rely on your own assessment of the problem. Take notes on your dog's symptoms and bring them with you to the vet visit.
