Can a scratched cornea heal on a dog?

A dog’s eyes are delicate, and a scratched cornea—often from rubbing against rough grass, chasing a stray branch, or tussling with another pet—can be more than just a minor annoyance. Many pet owners wonder if such injuries heal on their own, and the answer depends on the severity. A superficial scratch, like a tiny nick from a blade of grass, might mend in a few days with proper care, but deeper wounds can lead to infections or scarring if left untreated.

Signs that your dog has a scratched cornea are usually hard to miss. They might squint constantly, keeping the affected eye half-closed to avoid light. You might notice excessive tearing, or the eye could look red and inflamed, with a cloudy film over the surface. Some dogs paw at their face relentlessly, trying to soothe the irritation, which can make the injury worse. If you see these behaviors—especially after a romp in the yard or a run-in with a bush—it’s time to act. Ignoring the signs can turn a simple scratch into something more serious, like a corneal ulcer, which takes longer to heal and often requires veterinary intervention.

Mild cases can sometimes heal with at-home care, but only under veterinary guidance. Your vet might recommend an antibiotic ointment to prevent infection and a cone collar to stop your dog from rubbing the eye. Never try to treat a suspected scratch with over-the-counter human eye drops—many contain ingredients that are toxic to dogs.It’s a good reminder that while some issues seem minor, consulting a professional is often the safest bet.

Deeper scratches or ulcers rarely heal without help. These injuries can expose the inner layers of the cornea, making it vulnerable to bacteria or fungi. Vets might use a special dye to highlight the extent of the damage during an exam, then prescribe stronger medications or even perform a procedure to protect the eye, like a temporary contact lens or a graft.

Recovery time varies. A small scratch might clear up in 3-5 days with consistent treatment, while a deeper injury could take weeks. Throughout the process, monitoring your dog’s behavior is key: if they stop squinting, their eye looks less red, and they’re no longer pawing at their face, those are good signs. But if symptoms worsen—like increased discharge or a refusal to open the eye—call your vet immediately.

In the end, a scratched cornea can heal, but its chances depend on how quickly you act and the injury’s severity. Prioritizing vet check-ups, using protective gear like cone collars as directed, and knowing the signs of trouble can make all the difference. After all, keeping your dog’s eyes healthy isn’t just about comfort—it’s about ensuring they can keep exploring the world, whether that’s chasing a ball in the park or napping in the sun, with the clear vision they deserve.
