Conjonctivite chez le chien

Dogs conjunctivitis

Aperçu

  • Conjunctivitis means inflammation (swelling) of the ‘conjunctiva’ and can be caused by many different conditions. The conjunctiva is a very thin layer of tissue that covers the inside of the eyelid and runs across the front of the eye. Conjunctivitis causes red, itchy, weepy eyes.
  • Always contact your vet if you notice anything wrong with your dog’s eyes – they are too important to ignore. If your dog suffers from conjunctivitis regularly, your vet will investigate why.

What are the symptoms?

Conjunctivitis can affect one or both eyes. Common signs include:

  • Pink or red eye(s)
  • Weepy eye(s)
  • Swollen eye(s)
  • Closed eye(s)
  • Rubbing their eye(s) or face
  • A cloudy appearance to eyes (blue eyes)
  • Blinking more than usual
  • Off food, unwell in themselves.

Quand contacter votre vétérinaire ?

Contact your vet if you notice any of the symptoms above or if you have a suspicion there is something wrong with your dog’s eye(s). If conjunctivitis is left too long without treatment, it can lead to serious problems or even loss of an eye.

If your dog suffers with conjunctivitis regularly, your vet will check for any conditions that might be causing it.

You know your dog best. If they don’t have the symptoms listed above but you are still concerned it’s always best to contact your vet.

Causes of conjunctivitis in dogs?

  • Irritants
    Your dog’s eyes are likely to become inflamed if they come into contact with something irritating for example smoke, dust, sand, or acid.
  • Bacterial infection
    -Many bacteria can cause eye infections.
    -If your dog suffers regularly from bacterial infections in their eyes, there is likely to be a reason (such as dry eye or an in-growing eyelash).
  • Allergy
    Allergies such as atopic dermatitis (atopy) often affect the skin around the eyes. Dogs with atopy suffer from conjunctivitis much more often than dogs with healthy skin.
  • Dry eye (Keratoconjunctivitis sicca)
    -Dry eye is a very common cause of conjunctivitis in dogs.
    -Dogs with dry eyes don’t produce enough tears which means their eyes become dry and inflamed.
  • Eye ulcer (corneal ulcer)
    -Eye ulcers are injuries (such as scratches or grazes) on the front of the eye.
    -Eye ulcers can become very serious if not treated quickly.
  • Eyelash disorders
    Eyelash disorders such as eyelashes growing from the wrong place or in the wrong direction.
  • Eyelid disorders
    Eyelid disorders such as eyelids that turn in (entropion) or are too baggy (ectropion).

  • Glaucoma
    Glaucoma is increased pressure in the eye. An eye with glaucoma will usually look cloudy and as though it is bulging.
  • Exposure keratitis
    -Exposure keratitis is a condition that means the eyelids don’t protect the front of the eye properly, it becomes dry and inflamed as a result.
    -Exposure to keratitis is a very common condition in short-nose breeds of dogs (such as the Shih Tzu).
  • Something stuck in the eye
    Something stuck in the eye (i.e. a grass seed).
  • Uveitis
    Uveitis is inflammation inside the eyeball.
  • Lens luxation
    Lens luxation is when the lens (a solid disc inside the eye) dislodges into the front of the eye.
  • Lumps and swellings in and around the eyes
    Lumps and swellings around the eyes can cause irritation and inflammation.
  • Pannus (chronic superficial keratitis)
    Pannus is a condition that causes a dog’s immune system to attack the front of the eye causing inflammation.
  • Viral infection
    -Some viruses can cause conjunctivitis.
    -Fortunately, they are very rare, probably because most dogs are vaccinated against them (e.g. Distemper virus and Adenovirus-1).
    -Remember to have your dog regularly vaccinated to protect them against conditions like this.

Traitement?

Treatment for conjunctivitis depends on the cause. Read articles on the conditions above for more information on each cause.

What if it doesn’t get better?

If your dog keeps getting conjunctivitis, they will need investigation by your vet. Investigations may include swabs, tear measurements, or perhaps a referral to a specialist ophthalmologist (eye vet).
Some conditions that cause conjunctivitis need lifelong treatment (for example atopy or dry eye).
