What causes a dogs eye to be red? Surprising Answer

Why Are My Dog’s Eyes Red?

Have you noticed that your dogs eyes appear bloodshot? Your dogs eyes could be red for a number of reasons. Here are some of the most common causes:

If a foreign object, such as dirt, dust, grass or hair gets in your dogs eye, it can cause irritation and redness. Cleaning sprays and perfume can also irritate your dogs eyes.

Signs of irritation:

  • Redness
  • Tears or watery discharge
  • Itchy eyes (expressed by pawing at their eyes or rubbing their face)
  • Treatment: You should contact your veterinarian first before any applying any treatment. They may suggest to gently wash out your dogs eyes with lukewarm water. Wait an hour or two to see whether the redness clears up.

    Just like people, dogs can have allergies, too. They can have seasonal allergies and food allergies, as well as allergic reactions to dust, mold, household cleaners and other environmental allergens. Any of these allergies can cause a dogs eyes to turn bloodshot, says the American Kennel Club.

    Signs of Allergies:

  • Redness
  • Tears or watery discharge
  • Itchiness
  • Licking and scratching
  • Sneezing
  • Red or inflamed skin
  • Hair loss
  • Treatment: Dont give your dog over-the-counter allergy medicine or eye drops without first consulting your veterinarian. Proper treatment depends on your dogs specific allergy, which your vet will determine by examining your dog and running tests. In some cases, pinpointing allergens can be a long process, especially if your vet suspects a food allergy (12-week food trials are required to properly diagnose food allergies).

    Pink eye, the common name for conjunctivitis, comes in two forms: infectious and non-infectious. Infectious pink eye is caused by a virus or bacterial infection, while the non-infectious type is generally caused by allergies, irritation, injury, a congenital condition or an illness such as distemper.

    Signs of Pink Eye:

  • Red or puffy eyes
  • Itchy eyes
  • Eye discharge
  • Eyelids sticking together, squinting
  • Swelling of the eyelid lining (conjunctiva)
  • Treatment: Whether or not your dogs case of pink eye is infectious, it needs to be checked out and treated by a vet. Theyll determine whether its the contagious type before determining and treating an underlying cause. Infectious pink eye must be treated with antibacterial or antifungal medicine. Your vet may also give you anti-inflammatory medicine to administer to your dog.

    Another issue that might cause you to wonder why your dogs eyes are red is dry eye, the common term for keratoconjunctivitis sicca (KCS). This condition occurs when the tear glands dont produce enough moisture, causing the tissues of the eye to dry out, says Cuteness. Dry eye can be a result of eye trauma, an underlying health condition or a corneal ulcer.

    Signs of Dry Eye:

  • Redness
  • Itchy, painful eyes
  • Thick discharge
  • Treatment: Your vet will conduct a test to assess the level of moisture your dogs tear glands are producing. They may also check for corneal ulcers. Dogs with dry eye are commonly prescribed eye drops to keep their eyes moist. Youll need to clean their eyes on a regular basis. While dry eye sometimes clears up on its own, it can also be chronic and require lifelong treatment.

    Glaucoma is a painful condition caused by fluid buildup that creates swelling and pressure, leading to damage of the optic nerve. If left untreated, glaucoma can lead to blindness.

    Signs of Glaucoma:

  • Redness
  • Pain
  • Swollen eyes
  • Receding eyeballs
  • Cloudy appearance
  • Dilated and unresponsive pupils
  • Poor vision
  • Treatment: If your dog shows signs of glaucoma, bring them to the vet immediately. If you manage to catch the condition early enough, theres a better chance that topical medicine or laser surgery will be effective and that your dogs vision can be saved, says Cuteness. In more severe cases, surgery may be required to relieve pain caused by fluid buildup and pressure. In the most severe cases, surgical removal of one or both eyes may be required.

    In addition to the causes listed above, red eyes in dogs can be a sign of an illness, such as distemper, or a chronic health condition like diabetes or hyperthyroidism. Red eyes can also indicate a tumor or certain types of cancer. Some dog breeds are more prone to eye problems than others, says Rover.com. This includes flat-faced breeds like pugs and bulldogs, as well as long-haired breeds whose hair can irritate or damage their eyes. Dogs also become more prone to eye problems and underlying health conditions that can cause eye redness as they age.

    How are my dog’s eyes different from mine?

    Our dogs eyes work a lot like ours. They are active organs that are constantly adjusting themselves, working to transmit what your pooch sees to their brain. Their eyes differ from ours in that they have a third eyelid, called the nictitating membrane, that is located in the corner of their eye.

    As you have surely experienced with your own eyes, there are a whole host of things that may cause irritation and redness, from external irritants to excessive dryness and disease. A number of dog breeds are more susceptible to developing red, irritated eyes as well as associated health conditions.

    Flat-faced breeds like Pugs, Bulldogs and Shih Tzus as well as breeds with long hair around their eyes like Sheepdogs, Maltese and Poodles can all be at greater risk of developing red eyes than other breeds. Older dogs often develop issues with their eyes causing them to become red more often, especially if they have pre-existing conditions like diabetes or high blood pressure.

    What If There’s A Red Spot In My Dog’s Eye?

    If you notice a small red spot in your dog’s eye, it could just be a minor broken blood vessel. This usually isn’t a cause for concern and should clear up on its own. However, if you notice several blood clots in the front of the eye or any other changes to your dog’s eye or vision, you should seek veterinary attention as soon as possible.
