Conjunctivitis In Dogs

Conjunctivitis In Dogs

As a dog owner, you want to know about any and all illnesses which could harm your dog or make their health worse. But of course, unless you are a certified veterinarian, you can’t be aware of every single thing that could go wrong with your dog. Just like with your own body, the best way to keep track of your dog’s health is to keep a close eye on them, and notice any changes in their body weight, shape, energy levels or physical appearance.

When it comes to your dog’s eyes, they don’t require any maintenance unless they are showing signs of unhealthy change. Some dog breeds, especially purebred dogs, such as spaniels and poodles, can be prone to eye problems. However, any dog, of any age, can experience conjunctivitis.

Symptoms of Conjunctivitis in Dogs

There are common symptoms of conjunctivitis which you could spot on your dog’s eyes. If you are concerned about your dog’s health in any way you should seek professional advice from a vet.

Eye discharge

Like in humans, conjunctivitis is an infection which usually produces a discharge which can be clear, yellow or green. You will spot this in the corner of your dog’s eye - it can look like your dog’s eye is weeping.

Red eyes

The white parts of a dog’s eye are much smaller than our whites, but nevertheless you will be able to tell a difference if your dog has conjunctivitis. The white part around the very edge of your dog’s eye will be red and bloodshot.

Swollen eyes

If your dog has conjunctivitis, one or both of his eyes could be swollen. It will likely be very uncomfortable for him, so make sure you see a vet as soon as you spot the swelling.

Itching, pawing, or excessive blinking

If your dog’s eye is very itchy or causing him discomfort you may be able to tell through his behaviour, such as scratching or pawing at the eye a lot. Your dog might also be blinking a lot or rubbing his face on objects to try to itch his eye.

Causes of Conjunctivitis in Dogs


If the pollen count is high in your area or your dog has encountered something he is allergic to, the irritation can cause conjunctivitis.

Insect bites

Any bite or irritation to the eye can cause conjunctivitis.

Bacterial infection

This is less common, but a bacterial infection in or around your dog’s eye can produce conjunctivitis symptoms too.

Dog Conjunctivitis Treatment

If your dog has these symptoms, the vet will likely prescribe drops for you to put into your dog’s eye for a few days. The infection should clear. If it is more serious, antibiotics can also be prescribed which you mix in with your dog’s food.


If you spot any of these signs, it’s best to seek professional veterinary advice. Your dog might be uncomfortable, and an untreated eye infection can lead to larger problems. Better to be safe than sorry!
