Eye Injury in Dogs

See your vet immediately if you think your dog has an eye injury. Eye problems can look mild at first, but the surface of the eye is delicate and painful. A small scratch can turn into a deeper corneal ulcer, and deeper injuries can threaten vision or even the eye itself. Dogs with eye trauma often squint, keep the eye closed, rub at the face, tear excessively, or develop redness, discharge, or a cloudy blue-white appearance.

In dogs, many eye injuries affect the cornea, the clear front surface of the eye. Trauma may come from rough play, sticks, plant material, cat scratches, self-trauma from rubbing, chemical exposure, or blunt impact. Some dogs also have underlying problems that make injury more likely or healing slower, including dry eye, eyelid abnormalities, or flat-faced anatomy. Because pain, infection, and corneal melting can progress quickly, prompt veterinary care matters.

The good news is that many dogs recover well when treatment starts early. Your vet will look for the cause, check whether the injury is superficial or deep, and build a treatment plan that fits your dog’s needs and your family’s budget. Spectrum of Care means there is often more than one reasonable path, from conservative medical care to advanced ophthalmology procedures, depending on severity and goals.

Common causes of eye injury in dogs include scratches from plants, dirt or sand trapped under the eyelid, cat scratches, rough play, running through brush, and rubbing the eye on carpet or furniture. Blunt trauma can also injure the eye after falls, collisions, or being hit by an object. Chemical exposure is another concern, especially with household cleaners or other irritating products. In some cases, a foreign body may be stuck under the eyelid or on the cornea.

Not every painful eye starts with a dramatic accident. Corneal ulcers can also develop secondary to dry eye, eyelid problems, abnormal eyelashes, exposure from a prominent eye, or chronic irritation. Flat-faced breeds may be at higher risk because their eyes are more exposed. If a dog has one cloudy, painful eye, trauma is often high on the list, but your vet also has to consider glaucoma, uveitis, infection, and other eye diseases that can mimic injury.

A helpful way to think about causes is direct injury versus underlying vulnerability. Direct injury includes punctures, abrasions, and blunt trauma. Underlying vulnerability includes dry eye, poor tear film, conformational issues, and chronic corneal disease. Your vet will try to identify both, because treating the wound alone may not be enough if the reason it happened is still there.

See your vet immediately if your dog is holding the eye shut, crying out, pawing at the face, has sudden cloudiness, blood in or around the eye, a visible cut, a puncture, marked swelling, or the eye looks bulged, sunken, or out of place. These signs can point to a corneal ulcer, perforation, glaucoma, severe inflammation, or deeper trauma. Eye injuries should be treated as urgent because delays can increase pain and raise the risk of scarring or vision loss.

You should also contact your vet promptly for redness, tearing, yellow or green discharge, light sensitivity, a raised third eyelid, or any change in the eye’s normal shape or clarity. Even if your dog still seems comfortable, a small corneal injury may be present. Dogs do not always show the full extent of pain, and some ulcers are only visible with stain and magnification.

Until your dog is seen, prevent rubbing with an e-collar if you have one, keep the face clean and dry, and avoid putting anything in the eye unless your vet has told you to use it. Do not use leftover medications from a prior eye problem. Steroid-containing eye drops can worsen ulcers and may increase the risk of serious complications if the cornea is damaged.

Your vet will start with a careful eye exam and a history of what happened, when signs started, and whether your dog has had eye disease before. They will look for squinting, discharge, corneal cloudiness, eyelid swelling, third eyelid elevation, and any obvious foreign material or wound. A full physical exam may also be important if the injury happened during a fight, fall, or car-related trauma.

One of the most common tests is fluorescein stain. This dye sticks to damaged corneal tissue and helps your vet identify scratches and ulcers. Your vet may also perform a Schirmer tear test to measure tear production, since dry eye can contribute to ulcers or slow healing. In many cases, they will check intraocular pressure to screen for glaucoma or uveitis, but this may be delayed if a globe rupture is suspected. Magnification, eyelid eversion, and sometimes sedation are used to look for hidden foreign bodies or deeper damage.

If the ulcer is deep, infected, melting, recurrent, or not healing as expected, your vet may recommend corneal cytology, culture, repeat staining, or referral to a veterinary ophthalmologist. The goal is not only to confirm that an injury is present, but to determine how deep it is, whether infection is involved, and whether medical care alone is likely to be enough.

Home care starts with protecting the eye from more trauma. Use the e-collar exactly as your vet recommends, even if your dog seems less painful after the first day. Give eye medications on schedule, wash your hands before and after, and avoid touching the bottle tip to the eye. If your dog has more than one eye medication, ask your vet how many minutes to wait between them.

Watch closely for worsening pain, more squinting, thicker discharge, increasing cloudiness, swelling, or any change in vision or behavior. Deep or complicated ulcers may need rechecks every 1 to 2 days, while simple ulcers are often rechecked within about 5 to 7 days. Healing cannot be judged by comfort alone. Some dogs seem brighter before the cornea is fully healed, which is why follow-up staining is so important.

Do not use human eye drops, redness relievers, or leftover pet medications unless your vet specifically approves them. Some products can delay healing or make an ulcer worse. If your dog seems more painful after a medication, stop that medication and call your vet right away. Long term, your vet may also look for dry eye, eyelid issues, or breed-related exposure problems so future injuries are less likely.
