Dog conjunctivitis, also known as pink eye, is a condition caused by the inflammation of the conjunctiva, a thin, transparent membrane that covers the front part of the eyeball and lines the eyelid.
What are the symptoms of dog conjunctivitis?
In humans, we can quickly notice when our eyes become red, itchy or sore, which makes conjunctivitis one of the easiest problems to spot. But in dogs, the white part of their eyeball is not as readily visible, especially if they have long eyebrow hair. So, it’s important to be on the lookout for other symptoms your pet might be experiencing. Here are some of the most common signs of conjunctivitis in dogs:
- Eye discharge (yellow or green)
- Squinting
- Watery eyes
- Eyelids that stick together
- Excessive blinking
- Rubbing their eyes
- Swollen eyelids
These signs may be accompanied by cold-like symptoms, such as a runny nose, which can indicate a virus.
What causes conjunctivitis in dogs?
Dogs love to explore every nook and cranny, but this also means they can easily get exposed to all sorts of triggering factors of conjunctivitis, from viruses or bacteria to material such as dirt or grass seeds that find their way into the eye. These are some of the most common causes leading to a swollen, red or weepy eye:
- Irritation from foreign objects (these are often hidden under the eyelids and can be hard to spot)
- Smoke, mould, dust or pollutants in the environment
- Dry eyes that don’t produce enough tears
- Allergies
- Other eye problems such as glaucoma or a tumour
- Injury of the eye area
- Shampoo that irritates the eyes
- Ingrowing eyelids or hairs rubbing on the surface of the eye
- Bacterial infection
- Viral infection
- Mites that affect the skin around the eyes
It can be difficult for pet owners to narrow down the list and get to the correct cause of their dog’s eye problem themselves, so it’s always best to ask the vet for advice. Determining the cause of conjunctivitis in dogs is important, as this will decide the most effective treatment for your pet.
Dog conjunctivitis treatment
With so many potential factors able to trigger dog conjunctivitis, there isn’t a standard treatment that can be applied in every case. This is why your vet will first establish the cause before recommending any course of action. Pain relief might also be needed as having a sore eye isn’t very pleasant for your dog.
If a foreign object is behind your dog’s eye problem, your vet will usually try and remove it. In some cases, this may require sedating your pet to make the process easier and remove the risk of your dog becoming too restless and causing an eye injury during the procedure.
If a bacteria or virus is the cause of your dog’s conjunctivitis, treatment in the form of antibiotics or antiviral medication will be recommended.
