How to know if your dog is losing vision or has gone blind already?

Dilated pupils that don't constrict when exposed to light can be a sign of blindness or decreased vision and usually signifies a problem with the retina, optic nerve, or the brain. Pupils can also dilate from certain toxins. I would recommend having your vet examine Max's eyes if you're concerned.

It can be tricky to determine if newborn pup is [blind](https://www.petcoach.co/dog/condition/blindness/) since puppies don't [develop full eyesight](https://www.petcoach.co/article/sight-development-in-the-dog-puppy) until around 8 weeks of age. Vision will gradually improve to adult capacity over the next several weeks. You can gauge your puppy's vision by throwing a cotton ball into the air and watching his/her response. A puppy with normal sight will watch the hand motion, then the cotton ball as it falls to the floor. Do this silently as sound may distract the puppy. If your pup fails to spot or follow the cotton ball, see your veterinarian or a [veterinary ophthalmologist](https://www.acvo.org/) for a complete eye exam.

Hello, that reflection in your dogs eyes appears like norma tapetal reflection. Red eyes do not always indicate blindness, so I wouldn't create that association with your dog's eyes. More so, look for any signs to bumping into things, being startled, looking into space and being unable to find his food bowl. These would be more likely to be consistent with blindness. Hope this helps and best of luck.

Based on what you have done so far, I would say that it certainly is likely that Willow is visually impaired.

Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Dogs can develop blindness secondary to disease of the brain (central), eye (peripheral) or secondary to systemic disease such as elevated blood pressure or Cushing's disease. If she is able to see now, she may not have been truly blind before or just had trouble seeing at night. A full examination would be needed to help to determine the underlying cause. In the meantime, observe her closely and make notes including changes in behavior, bumping into things, changes in eyes, changes in urination or defecation, appetite and take this information with you to your veterinary appointment.

The pupil can constrict with bleeding or inflammation in the anterior chamber of the eye, blunt trauma, or a scratch to the surface of the eye. If you see blood, if your dog is squinting or seems painful, or if there is discharge from the eye I’d recommend traveling to see an emergency vet if at all possible since some conditions could compromise vision if left untreated. Otherwise I think you could monitor her for a day but if the pupil does not return to normal within 24 hours I’d recommend seeing a vet.

Sadly, many of the ailments of human senior citizens can also occur in our canine companions. Impaired vision or blindness can occur in dogs and can be due to things like cataracts, glaucoma, etc. The good news is that these diseases, if caught early enough, can be treated and sometimes even reversed or cured! My best advice is to take Baby to your local veterinarian as soon as possible to have a complete ophthalmic examination performed. Some of the tests you should ask for are as follows: a menace test, intraocular tonopen test, schirmer tear test, and fundic exam. I hope this helps. Have a great day.
