My puppy's eye is cloudy and one pupil dilated after injury. What now?

Updated on September 23rd, 2025

Pet's info: Dog | Chesapeake Bay Retriever | Male | unneutered | 4 months and 11 days old | 35 lbs

My puppy was playing with my kids and got hit in the eye or eye area with his toy (a rope). He yelped, but since seems ok, except one eye appears to be cloudy, and only one pupil dilated.

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.

Ouch, poor Massimo! When one eye is dilated, that is called anisocoria. It can occur when there is trauma to the eye, and a sudden appearance of it requires an immediate trip to the vet. A cloudy eye can also be seen with anisocoria. Any eye condition is considered an emergency, as leaving them untreated can lead to vision loss. I would take Massimo into an ER vet now, or find a vet on call to see him right away, as he needs his eye treated immediately.

The eye does not look right. you cannot trust what a breeder tells you unfortunately as they will say anything to sell a puppy, especially one that has a medical issue. i strongly recommend that you take him yourself to a vet if you want a definitive answer, this is not something that can be checked over the internet, the eye needs to be examined physically by a vet in order to access the condition.

My puppy's eye is foggy after a bush poke. Is it an emergency?

Cloudy eyes should always constitute an emergency vet visit. Since you know there is possible trauma, there could be an abrasion or corneal ulcer, something stuck under an eyelid, a hole in the cornea, or severe inflammation. There are several eye tests the vet may recommend after examining the eye to determine the most appropriate treatment.

My dog has one dilated pupil after neutering. Is it an emergency?

Yes, that is definitely something you should be worried about. What you are seeing is called anisocoria, and when it suddenly appears, it is a medical emergency. This can be due to corneal injury, disease or injury to the brain, disease or injury to the nerves running to the eye, or uveitis among other causes. I would take Ace into an ER vet or find a vet on call to see him ASAP to diagnose what is causing the anisocoria so it can be treated.

My puppy has one dilated eye, but she's acting normal. Should I worry?

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.

What to do if my dog's eye is cloudy after a tennis ball injury?

I am sorry to hear about your dog. I would recommend taking him in to the vet as soon as possible, including the emergency vet if your vet isn't open. This could be corneal edema or a corneal ulceration. We could also possibly have trauma within the eye that we cannot see due to the cloudiness of the cornea, such as bleeding of retinal vessels or trauma to the optic nerve and the earlier the eye is treated the better the chance of healing and preserving vision.

My 3-week-old puppy has a cloudy eye with a pink lump. What's wrong?

I recommend to get this puppy examined today. That eye looks inflamed and possibly infected. It's possible this is a congenital anomaly but the appearance of the eye looks suspicious for something is trapped in the eye (hair or or object) or that a virus has causes a painful corneal abrasion. The opacity may represent corneal edema which is very worrisome. It's possible he is in pain so get this addressed quickly. Best of luck.

My puppy hit his head, one eye is bigger. Should I be concerned?

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Oso definitely should be fully checked by your local vet. Difference in pupils size can be caused by ocular trauma (for example blunt trauma to the eye when Oso hit the bench) or less frequently, by brain concussion / brain trauma. Your vet will be able to distinguish between these two problems and recommend treatment, if required.

Dog's pupil small after dog fight, can't get to vet. What should I do?

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.
