My dog has dilated pupils and walks head down. Is he going blind?

This can be a sign of an eye problem - the eye can dilate if a toxin has been ingested, or it's possible that the other pupil is actually constricted secondary to pain or a scratch on the eye. I'd recommend seeing your veterinarian for an exam of the eyes. If Nova seems to be painful or disoriented I"d recommend seeing an emergency veterinarian today.

Poor pup! Cloudiness and anisocoria (the medical term for unequal pupils) are signs of a significant eye injury. It would be best to have Massimo examined by an emergency vet tonight if possible. If this isn't an option for you, he should be seen by your regular vet first thing in the morning. Prompt assessment and treatment is important in cases like this because the risk of permanent damage or vision loss increases the longer he goes without treatment.

If your pet hit the wall hard enough with his head, yes it is possible that his brain could have been hurt. A sign of that is one pupil smaller than the other. This is known as anisocoria, and it is a sign of trauma to the brain. If you see this sign in your pet, it's quite serious, and he needs to see a vet immediately.

Poor girl. This breed is prone to several disorders that can cause this including: hepatic encephalopathy, hydrocephalus, a brain tumor, or even just vestibular disease. I would highly recommend taking her in to your vet for further testing (ie Bloodwork +/- xrays) as soon as possible. I hope that your fur baby I able to become stable soon! It’s best to just keep her calm and no extrenuous activity until she can be seen and evaluated. Best wishes and take care!

This could be caused by trauma to the eye, the nerves leading to the eye, or even the brain. It could also be caused by an infection. It's very concerning when there's a problem with the eye such as this, and it requires an immediate vet visit. That's because leaving it untreated can lead to permanent vision loss. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck.

Poor Beau! The eye not dilating is likely a sign of significant head trauma, which also makes sense if he lost a tooth in the collision - it normally takes quite a bit of force to cause this! It sounds like Beau may have a concussion or other serious head injury, and it also sounds like his tooth socket may be infected - especially if part of the tooth root is still present. These things will need veterinary care right away, so I would recommend taking him to the vet today to be checked. Your vet can do a complete neurologic exam to help determine how serious his head injury is, and will also evaluate his mouth to see if he needs surgery to remove any remaining part of the tooth that may be infected and causing pain.

Pupil reflex is the best way to determine if there is blindness, the pupil is the most central part of the eye, if you take a flash light in the dark and direct it toward the eye at once you will see the pupil constrict, this is a sign that the eye works properly in most cases.
