If your dog’s eye is bleeding, keep your dog calm, prevent them from pawing at the eye, and get to a veterinarian as soon as possible. Eye injuries in dogs can deteriorate within minutes, and even a delay of a short time can mean the difference between saving and losing vision. Do not attempt to treat the eye yourself or remove anything stuck in it.
What to Do Right Now
Your first priority is stopping your dog from touching the injured eye. Dogs in pain will paw at their face or rub it against furniture and carpet, which can turn a minor injury into a severe one. If you have an Elizabethan collar (the plastic cone), put it on immediately. If you don’t have one, gently restrain your dog or have someone hold them while you prepare to leave for the vet.
Do not put any human eye drops in your dog’s eye. Many over-the-counter redness-relief drops contain an ingredient called imidazoline, which constricts blood vessels and can be harmful to dogs. Don’t apply pressure directly to the eyeball, and don’t try to rinse blood out of the eye unless a chemical splash caused the injury. If something like a cleaning product did get into the eye, flush it with plain water or a homemade saline solution (two teaspoons of table salt dissolved in one quart of water) for at least 15 minutes, then head to the vet.
If the eye appears to be bulging out of the socket, keep it moist with water, contact lens saline, or K-Y jelly applied gently to the surface. Do not try to push the eye back in. This requires anesthesia to avoid damaging the inside of the eye.
What Causes a Dog’s Eye to Bleed
Bleeding can come from outside the eye or from inside it, and the distinction matters because the causes and urgency differ.
External bleeding usually involves the eyelid, the surface of the eye, or the tissue around it. The most common culprits are scratches from other animals, thorns or branches during walks, and blunt impacts. A torn eyelid will bleed visibly and look alarming, but a scratch on the cornea (the clear outer surface) may produce only a small amount of blood mixed with tears. Foreign objects like plant material can also become lodged under the eyelid, causing ongoing irritation and bleeding.
Internal bleeding, where blood pools inside the eye itself, is called hyphema. You might notice a red or dark layer settling in the lower portion of the eye’s clear front chamber. This type of bleeding has a wide range of causes: blunt trauma to the head (from car accidents or fights with other animals), high blood pressure, infections, blood clotting disorders, inflammation inside the eye, and in some cases, tumors. Because hyphema can signal a serious systemic problem, your vet will likely want to investigate beyond just the eye.
Signs That This Is an Emergency
Any bleeding from or inside the eye warrants veterinary attention, but certain signs mean you should go immediately rather than waiting for a regular appointment. Rush to a vet if your dog is keeping the eye completely shut and refusing to open it, if there is thick discharge along with the bleeding, if the cornea looks cloudy or hazy, or if you can see a visible dip or bulge on the eye’s surface. A dog that is rubbing their face hard against the floor or furniture is signaling intense pain.
If the bleeding is minor, with just slight redness, occasional squinting, or a bit of extra tearing, you still need a vet visit, but it’s reasonable to call ahead and get seen within 24 hours rather than racing to emergency care.
What the Vet Will Do
The veterinarian will start with a thorough eye exam, often using a special dye called fluorescein that glows under blue light. This dye sticks to damaged areas on the cornea, revealing ulcers or scratches that aren’t visible to the naked eye. They’ll also likely measure your dog’s eye pressure to check for conditions that could threaten vision, and test tear production to rule out dry eye as a contributing factor.
If the vet suspects hyphema or internal bleeding, expect bloodwork and possibly an ultrasound to look for underlying causes like clotting problems, infection, or high blood pressure. For more severe or complicated injuries, your vet may refer you to a veterinary ophthalmologist.
Emergency vet visits typically cost $1,000 or more depending on your location and what diagnostics are needed. Bloodwork runs $80 to $400, and ultrasound imaging ranges from $300 to $800. These costs can add up quickly, so it helps to call ahead and ask what to expect.
Recovery and Healing Time
How long your dog’s eye takes to heal depends entirely on the type and depth of injury. A superficial corneal scratch typically heals in about one to two weeks with proper medication. Deeper ulcers take longer, with a median healing time around 19 to 21 days in studies. Older dogs (over 10 years) tend to heal more slowly, sometimes needing up to 30 days or more. Your vet will schedule follow-up visits to re-stain the eye and confirm that healing is progressing.
Hyphema recovery varies even more widely because it depends on treating the underlying cause. If trauma caused the bleeding and no other structures were damaged, resolution can take a few weeks. If a systemic condition like high blood pressure is responsible, the eye won’t fully recover until that condition is managed.
Why the Cone Matters
Your vet will almost certainly send your dog home in a rigid plastic Elizabethan collar, and keeping it on is one of the most important things you can do. Dogs will rub healing eyes on carpet, furniture, pillows, and blankets, even while sleeping. This can tear open a healing wound, introduce infection, or break down surgical repairs. A single moment of unsupervised rubbing can undo days of healing and lead to additional surgery.
Soft fabric or inflatable collars are not sufficient for eye injuries because they still leave the face exposed. The American College of Veterinary Ophthalmologists specifically recommends a firm plastic cone that extends to the tip of your dog’s nose. This length still allows them to eat and drink from their bowls normally, as long as the collar is properly sized. If the collar seems too long and your dog can’t reach food or water, ask your vet to adjust the fit rather than switching to a softer alternative.
Many owners worry their dog “won’t tolerate” the cone, but most dogs adjust within a day or two. Patience and positive reinforcement, like treats and calm praise, help significantly during that transition period. Even if you think your dog isn’t rubbing the eye, you can’t watch them 24 hours a day. The cone stays on until your vet says otherwise.
