To determine whether a dog's eyes are blind, the owner can use a flashlight to shine into the dog's eyes to see if the pupil will shrink. If the dog's pupil does not shrink, it is likely to be blind. Secondly, the owner can also judge by observing the dog's behavior. If the dog often hits walls or other obstacles while walking, it is very likely to be blind. Of course, the most direct way is to take your dog to the hospital for an eye examination.

1. Use a flashlight to shine into the dog’s eyes

A dog with normal eyesight will have its pupils contract when exposed to a flashlight or other strong light. Therefore, owners can use strong light to stimulate the dog's eyeballs to see if the dog's pupils shrink. If the dog's pupils do not shrink after encountering strong light stimulation, it can prove that the dog's eyes are blind.

2. Observe the dog’s behavior

After a dog becomes blind, he will have some abnormal behaviors, such as not knowing how to avoid obstacles in front of him and often bumping into them. Go to the wall, put the food it likes to eat not far from it, but it can't find the direction. If this happens to your dog, it can also mean that your dog may be blind.

3. Go to the hospital for an eye examination

If you are still not sure whether your dog is blind through the above two methods, then the most reliable way is to take your dog directly to the pet hospital. Get an eye exam. If it is determined that the dog is really blind, it must receive treatment as soon as possible so that the dog can recover as soon as possible.
