How do you treat a dog's cornea?

Dog’s cornea is that clear outer layer protecting their eye, and when it gets hurt—whether from a scratch during a romp in the woods or a foreign object like dust—you’ll notice signs quickly. They might squint, paw at their eye, or keep it shut, and the area could look red or cloudy. Acting fast matters, but knowing the right steps without overstepping is key, especially with local laws in mind.​

First, resist the urge to rub or rinse the eye with just any water. Tap water can carry bacteria, and rough handling might make things worse. Instead, gently hold a clean, damp cloth near the eye to let them blink naturally—this can help dislodge small debris. If they’re in obvious pain, though, it’s time to call the vet. Many places have regulations requiring professional care for eye injuries to prevent infections that could spread to other animals.​

Your vet might prescribe antibiotic ointment to prevent infection, especially if the cornea is scratched. It’s crucial to follow their instructions exactly—skipping doses or stopping early can lead to complications. Also, keep in mind that some over-the-counter human eye drops can be toxic to dogs, so never use them without explicit approval. In regions with strict animal welfare laws, improper treatment could even result in fines, so err on the side of caution.​

While treating the cornea, protect your dog from further harm. Use an Elizabethan collar to stop them from pawing or rubbing the eye—annoying as it is, it’s non-negotiable for healing. Limit their activity too; running through tall grass or roughhousing with other pets increases the risk of re-injury. This is where knowing your local dog park rules helps—some areas require leashes if a dog is injured, to keep both them and others safe.​

Recovery times vary. Minor scratches might heal in a few days with proper care, but deeper ulcers could take weeks and may need more intensive treatments like medicated drops or even surgery. Watch for warning signs: increased redness, discharge, or a cloudy eye that doesn’t improve. These could mean the injury is worsening, and delaying a vet visit could lead to vision loss.​

Caring for a dog’s cornea isn’t just about easing their discomfort—it’s about being a responsible pet owner. Following local laws, working with your vet, and staying vigilant ensures your pup heals properly. After all, those bright eyes are how they show us so much love—keeping them healthy is the best way to return it.
