Poor Hank! It could be he has a serious eye infection leading to this cloudiness, squinting, and trouble seeing. He could have also injured his eye. It's very concerning this just happened overnight, and any problem with the eye should be considered an emergency. That's because leaving it untreated can lead to 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, I hope this helps!

If you can get to another vet more quickly, or even an emergency vet that would be best. Clouding of the eye may be due to an infection, illness or injury and waiting to have it treated could lead to a worsening of symptoms or even loss of the eye. Attempting to treat at home may worsen the problem or cause excessive irritation. It is best to seek veterinary care ASAP.

Poor Milo. It sounds like his eye is quite painful if he screams when you touch it. Any eye problem needs to be checked out by a vet promptly as leaving it untreated can lead to vision loss. I'd take him into a vet immediately to get his eye treated. Best of luck.

My dog's right eye is cloudy. Is it serious? Should I see a vet?

Poor Hurah! I can't see his eye very well in this photo, but any cloudiness is always cause for concern. Depending on the specific part of the eye that looks cloudy, this could be caused by glaucoma, a corneal scratch or ulcer, a severe eye infection, or cataracts. I would definitely recommend taking Hurah in to see a vet as soon as you are able to. He/she can examine the eye using a special stain if needed to help diagnose the problem and get him started on appropriate treatment.

This is an emergency, your vet should see you right away, if he refuses you have to take him to another vet that will see him today. cloudiness of the eye is a very serious symptom, there are several eye condition that could cause that but it is important to start the treatment urgently, otherwise permanent eye damage could occur.

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 older dog has a cloudy eye, but sees fine. Is it just aging?

Lily could have cataracts causing this cloudy pupil, but it could also be due to an eye infection or glaucoma. The eye is such a delicate and important structure that any problem with it should be considered an emergency. That's because leaving it untreated can lead to vision loss. I would have Lily seen by a vet immediately, who can diagnose what is causing her cloudy pupil and can discuss treatment options with you.

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's eye is droopy with a cloudy film. What should I do?

The film you are referring to may be Andy's third eyelid. In which case it is possible that he scratched or injured his eye- especially if he was normal this morning. Since these can be very painful and I would recommend taking him in and having his eye examined and possibly 'stained'- a test to rule out scratches. I hope this helps!

My dog's eye is cloudy, shut, and has discharge. What's wrong?

It could be that Hershey has a severe eye infection or could have suffered trauma to the eye. The eye is such a delicate and important structure that any problem with it should be considered an emergency and should never be treated at home. That's because leaving it untreated or attempting home treatment could go very wrong and lead to vision loss. I would take Hershey into the vet immediately. The vet can determine what is causing the eye problems, will let you know if it can be cured, and can prescribe treatment for it.
