Why Do Dogs Get Eye Boogers?

Does your dog get eye boogers often? You’re not alone.

Eye discharge in dogs is normal, however you need to make sure to look out for yellow discharge or pus that can indicate infection. There are 5 common causes of eye discharge in dogs that we will look at.

1. Conjunctivitis

Also known as Pink Eye, this is the inflammation of tissue that covers the front part of the eyeball and lines the eyelid. Common symptoms include: eye discharge, excessive blinking, redness and swelling around the eyes. Although typically seem in both eyes, it can only affect one in certain conditions. Common causes include: bacterial infections, allergies, tumors, inflammation from pollutants such as smoke, and more. The treatment will depend on the cause and may include antibiotics, pain medication, antihistamines, and possible surgery.

2. Canine Dry Eye

This condition can result from inadequate tear production or tears evaporating too quickly. Symptoms include: irritation, redness, discharge, some blink or squint excessively, and some hold their eyes shut. Typically affects both eyes, but one may appear worse than the other. Common causes include: hypothyroidism, canine distemper virus and immune disorders that damage the tear producing glands. Canine dry eye can lead to Corneal Ulceration, which has potential to impact your dogs vision due to the scarring it causes. Treatment depends on the severity and may include artificial tears, antibiotics or surgery.

Epiphora

This condition is an overflow of tears from the eyes.  It is often the symptom of something else going on, and is associated with a variety of conditions. If your dog is producing more eye discharge than normal, it’s a good idea to take them to a vet to determine the underlying causes. Common symptoms include: abundance of wetness around the eyes, and a reddish or brown staining on the fur. Depending on the cause, treatment may include antibiotics, steroids or surgery.

Entropion

This condition is a genetic condition where a portion of the eyelid is folded inward. This can cause hair on the surface to rub against the cornea, and can eventually lead to corneal ulceration or perforation. The damage can lead to a build up of scar tissue that can interfere with vision. Common symptoms include: squinting, excessive tears, and mucus discharge from the outer corners of the eye. The treatment is corrective surgery.

Breed Specific Issues

Certain breeds of dogs are more susceptible to developing eye issues such as excessive eye boogers or discharge. Exophthalmos is the bulging of the eye out of orbit and is common amongst short nosed breeds such as pugs. Dogs with bulging eyes are more likely to have eye problems because their eyes are more exposed and accumulate foreign material. Breeds with a lot of loose skin, such as Cocker Spaniels are more prone to ectropion – eyelids that roll outward – and cherry eye – a gland in the eyelid falls out of position.

Excessive or abnormal eye discharge can be a sign of a serious issue for your dog. It’s best to have them checked by your veterinarian and get a proper diagnosis and treatment plan.
