But how serious is it really? How does it occur? And how do you tell if that gunk in your dog’s eye is something to be worried about?
President of the Australian Veterinary Association, Dr Paula Parker, has the answers.
What are some reasons a dog may have discharge in its eye?
“A little crust or gloop can be normal in some dogs and is the equivalent to what we call ‘sleep’. Some breeds also accumulate a black or rusty coloured tear staining caused by a pigment called porphyrin, which is present in their tears.
“But there are other causes of discharge that are more serious. These include:
- Dry eye – where your dog is not producing enough tears to keep their eye(s) moist;
- Damage to the cornea (the front of the eye);
- Entropion, where the dog’s lower eyelid is turned inwards, and hair rubs on the eye;
Pets ain’t cheap. We all know this. But would you spend $4000 on a dog? (Post continues below.)
What is conjunctivitis, and what causes it to occur in dogs?
“Conjunctivitis is inflammation of the tissues surrounding the eyeball – the pink parts of the eye under the upper and lower eyelids.
“There are many causes of conjunctivitis in dogs, including physical injuries, foreign material irritating the eye (e.g. grit or grass seeds), allergies, chemical injuries, malformation of the eyelid, bacterial and viral infections. Infectious conjunctivitis from viruses is rare in dogs.”
