Understanding Bloodshot Eyes in Dogs
Bloodshot eyes in dogs can be a sign of various underlying health conditions. When a dog’s eyes appear red and irritated, it means that the blood vessels in the sclera (the white part of the eye) have dilated or expanded. This can be caused by a range of factors, including allergies, infections, injuries, or underlying health conditions.
It is important to note that bloodshot eyes in dogs can be a symptom of a more serious condition, such as glaucoma, uveitis, or cancer. Therefore, it is crucial to seek veterinary attention if the redness persists or is accompanied by other symptoms such as discharge, swelling, or discomfort.
One common cause of bloodshot eyes in dogs is an irritated sclera. This can occur due to allergies, dust, or other irritants in the environment. In such cases, the redness usually subsides within a few days, and the dog may not require treatment.
Another possible cause of bloodshot eyes in dogs is a subconjunctival hemorrhage. This occurs when the blood vessels in the sclera rupture, causing blood to accumulate in the surrounding tissues. Although this can be alarming, it is usually not a serious condition and resolves on its own within a week or two.
Common Causes of Bloodshot Eyes
Bloodshot eyes in dogs can be caused by a variety of factors. Identifying the underlying cause is crucial to providing the appropriate treatment. Here are some common causes of bloodshot eyes in dogs:
Foreign Object & Injury
Foreign objects such as dirt, dust, or grass can cause irritation and inflammation in the eyes, leading to redness. Injuries to the eye, such as scratches or blunt trauma, can also cause bloodshot eyes.

Treating Bloodshot Eyes In Dogs: 13 Treatment Steps & Options
If you notice that your dog’s eyes are red and bloodshot, it could be a sign of an underlying health issue, eye injury, or infection. Here are 13 treatment steps and options that can help alleviate your dog’s discomfort and treat their bloodshot eyes.
1. Flushing the Eye Out
Flushing out the eye with saline solution or water can help remove any debris or irritants that may be causing the bloodshot appearance. Use a syringe or eye dropper to gently flush the eye with the solution.
Rinsing a dog’s eye out with gloves to prevent contamination and using cool, sterile water or a veterinary eye cleanser can be done following these steps:
- Wash your hands thoroughly and put on disposable gloves to prevent any potential contamination.
- Position your dog in a comfortable and secure position. You may need someone to help hold the dog steady if necessary.
- Use a syringe, a gentle stream of cool, sterile water, or a veterinary eye cleanser recommended by your veterinarian. Make sure the solution is specifically made for eye irrigation and safe for dogs.
- Gently hold the dog’s head still, and with a steady hand, carefully direct the stream of solution into the affected eye.
- Allow the solution to flow over the eye, flushing out any debris or irritants. Use a generous amount of solution to ensure thorough rinsing.
- Avoid using cotton wool or any rough material, as it can scratch the surface of the eye and cause more damage.
- After rinsing, gently pat the area around the eye dry with a soft, clean cloth or tissue. Avoid touching the eye directly.
- Observe your dog for any signs of improvement or worsening of the condition. If the redness or irritation persists or worsens, seek veterinary attention promptly.
2. Saline Eye Drops & Eye Lubricants
Saline eye drops and eye lubricants can help soothe and moisturize your dog’s eyes, reducing redness and irritation. These can be purchased over-the-counter or prescribed by your vet. But first see our article on which eye drops are safe for dogs.
3. Treat Underlying Health Issue
If the bloodshot eyes are a symptom of an underlying health issue such as allergies, infection, or glaucoma, treating the underlying condition can help alleviate the redness.
4. Eye Compress
A warm or cool compress can help reduce inflammation and soothe your dog’s eyes. Use a clean, damp cloth and hold it against the eye for a few minutes at a time. A great eye compress is to make a cup of chamomile tea and simply let the tea bag cool. When it’s cool (but still wet) hold it against your dog’s eye for several minutes.
5. Use a Humidifier & Limit Sun or Smoke Exposure
A humidifier can help reduce dryness in the air, which can cause eye irritation. Additionally, limiting your dog’s exposure to smoke and sunlight can also help reduce irritation and redness.
6. Prevent Them from Scratching/ Rubbing the Eye
If your dog is scratching or rubbing their eyes, it can worsen the redness and cause further damage. Use an Elizabethan collar (the cone collar not the shock e collar) or other method to prevent them from touching their eyes.
7. Ointments & Medication
Your vet may prescribe topical ointments or medication to treat the underlying cause of your dog’s bloodshot eyes. Follow their instructions carefully and administer as directed. Remember that antibiotics have to be completed.
8. Reduce Exposure to Allergens
If allergies are causing your dog’s bloodshot eyes, reducing their exposure to allergens such as pollen or dust can help alleviate the redness.
9. Surgery: Medial Canthoplasty for Brachycephalic Ocular Syndrome
Some dogs have red eyes because their eyes protrude. We see this most often in short-nosed or brachycephalic breeds. In severe cases of brachycephalic ocular syndrome, surgery may be necessary to alleviate the symptoms and reduce the risk of long-term damage to the eyes.
You can see more on specific eye problems a dog may have in our article on dog breeds prone to poor eyesight.
10. Use a Harness Instead of a Collar to Stop Pressure on the Eye
If your dog is prone to eye injuries or has a history of bloodshot eyes, using a dog harness instead of a collar can help reduce pressure on the eye area. Remember, if a dog is pulling on a collar, the pressure on their throats can damage their eyes, possibly causing blood vessels to burst.
11. Treatment for Dry Eye
If your dog is suffering from dry eye, your vet may prescribe medication or recommend eye drops to help alleviate the symptoms and reduce redness. These are usually medications to stimulate tear production and eye lubricants.
12. Boost Dog’s Immune System
A healthy immune system can help reduce the risk of eye infections and other conditions that can cause bloodshot eyes. Make sure your dog is getting proper nutrition and exercise to boost their immune system.
13. Surgery for Eyelash and Eyelid Abnormalities
In some cases, eyelash or eyelid abnormalities like ectropion or entropion can cause bloodshot eyes. Surgery may be necessary to correct these issues and alleviate the redness.
Veterinary Diagnosis and Treatment
Diagnostic Tests
When a dog presents with bloodshot eyes, the veterinarian will conduct a thorough physical examination to determine the underlying cause. This may include a complete ophthalmic exam, blood work, and urine analysis. The vet may also use specialized diagnostic tests such as a Schirmer tear test, intraocular pressure measurement, or a fluorescein stain test to assess the eye’s condition.
Treatment Options
The treatment for bloodshot eyes in dogs will depend on the underlying cause. In some cases, the condition may resolve on its own, while in others, medical intervention may be necessary. Treatment options may include:
- Topical ophthalmic medications: These include eye drops or ointments that are used to treat infections, inflammation, or other eye conditions.
- Oral medications: Antibiotics, antihistamines, and other medications may be prescribed to treat underlying infections or allergies.
- Surgery: In some cases, surgery may be necessary to correct structural abnormalities or remove tumors that are causing the bloodshot eyes.
- Lifestyle changes: The vet may recommend changes to the dog’s diet, environment, or daily routine to help manage underlying health conditions that may be contributing to the bloodshot eyes.
It is important to follow the veterinarian’s instructions closely and administer any prescribed medications as directed. In some cases, it may take several weeks or months to fully resolve the condition, and regular follow-up appointments may be necessary to monitor the dog’s progress.
