White coats on your dog's eyes can be caused by a variety of reasons, including keratitis, corneal ulcers, or other eye problems. Some mild cases may have a certain ability to heal on their own, but if the tunica albuginea continues to worsen, it may lead to vision loss or even blindness. Therefore, even if some conditions may heal on their own, they cannot be taken lightly. Early detection and medical treatment are important means to protect the health of your dog's eyes.

If the white film on the dog's eyes persists or shows any signs of worsening, it is recommended to take it to the veterinary hospital for examination as soon as possible. Your veterinarian may determine the specific cause through a professional eye exam and decide on a specific treatment plan based on the cause.
