How to Judge if a Dog is Blind

To determine if a dog is blind, owners can use a flashlight to illuminate the dog's eyes and see if their pupils constrict. If the dog's pupils do not constrict in response to the bright light, it is likely that the dog is blind. Additionally, owners can observe the dog's behavioral responses to determine if they are blind. If the dog frequently walks into walls or other obstacles, they may have a vision impairment. Of course, the most direct method is to take the dog to a veterinarian for an eye examination.

Shine a flashlight into the dog's eyes

When a dog with normal vision encounters a flashlight or other sources of bright light, their pupils will constrict. Therefore, owners can use a strong light to stimulate the dog's eyes and see if their pupils show any constriction. If the dog's pupils do not constrict in response to the light stimulation, it can prove that the dog is blind.

Observe the dog's behavioral responses

After losing their vision, dogs will exhibit some abnormal behaviors, such as not knowing to avoid obstacles in front of them and frequently bumping into walls. They may also be unable to find their way to food placed nearby, even if it is something they love to eat. If your dog displays such behaviors, it could also indicate that they might be blind.

Visit a veterinarian for an eye examination

If neither of the above methods can determine whether or not your dog is blind, the most reliable option is to take the dog to a pet hospital for an eye examination. If it is confirmed that the dog is indeed blind, treatment should be sought promptly to help the dog recover as soon as possible.
