Causes Of Red Dog’s Eye And Ways To Treat It

Causes of red eyes in dogs

 The eyes of dogs become red or inflamed and appear red or pink for several reasons, and these are the most common:
Eye dryness: It occurs when the eye does not produce enough lacrimal secretions (tears are excreted in three layers: oily, watery, and mucous). Tears maintain the moisture of the cornea and keep it free from impurities, food residues and pathogens.
In the event of dehydration, the cornea becomes dry and inflamed; these infections are somewhat painful and make the eyes red. There are many causes of dry eyes, the most common of which is inflammation of the glands related to immune diseases, as it damages the tissues responsible for forming the aqueous layer.


  • Pink eye (conjunctivitis): It occurs when the conjunctiva becomes infected (the wet pink tissue that lines the inner eyelids and the whites of the eye).
    As this infection causes redness. Natural allergens (such as dirt and pollen) may also cause infection.
  • Cherry Eye: Dogs have a third eyelid that usually remains hidden, and some dogs have a genetic defect that weakens the ligaments that keep this eyelid in place, which makes the eyelid suddenly appear in the inner corner of the eye and looks like a cherry pill .. Therefore it is called Cherry Eye
  • Corneal damage: Anything that may damage the dog’s cornea causes eye redness, for example: if your dog runs in the garden and passes through tall grass or shrubs with long sharp leaves (such as short palms and cactus, for example) it may hurt his eye causing damage and irritation.


Other symptoms

Besides redness, you may notice some other symptoms:

  • Mucus secretion
  • Close the eye and open it excessively
  • Conjunctival swelling
  • Eye rubbing frequently
  • An increase in tears
  • The presence of scratches or scars in the cornea
  • The presence of a foreign body in the eye
  • A green or yellow filtrate from the eyes indicates an infection.

What do I do if I notice the red dog’s eye?

Eye problems in dogs are not always serious, but they require immediate attention. If your dog’s eyes turn red, contact the veterinarian and try to make an appointment on the same day, and when you call him, tell him a profile of redness, such as: when it occurs and other symptoms you see.



Do not try to diagnose and treat the red-eye yourself, as the veterinarian has the experience and equipment to thoroughly examine your dog’s eye and determine the cause of redness.

Also, do not delay taking your dog to the doctor, as eye problems may turn into more serious illnesses – and pain – if not treated quickly, the sooner you examine your dog, the better.

What are the symptoms and what are the treatment methods?

The doctor will perform a detailed examination of the eye and will determine the location of the reddish part of your dog’s eye. If the doctor suspects any corneal damage, he will place a few drops of green fluorescent dye on the cornea to see if there are any scars or scratches in it.


Your veterinarian will recommend treatment according to the cause of the redness, for example: if your dog has dry eyes, your doctor will prescribe a medication such as cyclosporine (which stimulates tear production) or may prescribe artificial tears.

If he has a Cherry Eye problem, then the third eyelid will be fixed surgically, and other treatments include anti-inflammatory and antibiotic medications.

Eye medications are usually ointments or eye drops. Before you leave the clinic, make sure you understand how to give the medication your dog needs. If you haven’t given your dog topical eye medication before, ask your vet to explain how to do this.

Remember that some dogs do not like eye drops or ointments, so you may need to be patient with your dog and set aside additional time to give him medicine.

Cure disease


How to treat your dog’s eyes after the initial treatment depends on the cause of redness. For example: In the event of dry eyes, you will need to give your dog regular topical medication, clean his eyes with the prescribed eyewash, and take him to follow-up appointments every six to twelve months.

If dust and pollen irritate your dog’s eyes, your doctor may recommend that you clean your house from dust repeatedly or reduce the time your dog spends outside when the pollen rate is high.

The cherry eye condition may return again after surgical treatment, so you will need to note the emergence of the third eyelid again.

Your veterinarian will help you determine the best measures to prevent red-eye in the future.
