We all worry about our pets’ health, which is why it’s important to know which diseases they are most prone to. In this respect, the eyes are one of the most exposed parts of a dog’s body. In this article, we explain the most common eye diseases in dogs and what to do in each case.

Prolapse of the third eyelid’s tear gland (cherry eye)
We’ll start with a frequent disorder, also known as cherry eye. It’s an excessive exposure of the tear gland, which irritates the eye’s surface and can lead to conjunctivitis. It’s a congenital defect seen in breeds such as the Beagle or the Cocker Spaniel. It’s treated with surgery to reposition the gland, although the problem can recur afterwards.
Conjunctivitis
This is an inflammation of the conjunctiva, accompanied by redness and discharge. Among the main causes are allergies (if both eyes are affected) and the presence of foreign bodies (which would affect only one). Working out the cause of the conjunctivitis is key to treatment, along with cleaning the affected eyes well and applying the antibiotic the vet prescribes.
Corneal ulcers
This is an injury that damages the middle and inner layers of the cornea as a result of trauma, though it can also be caused by dry keratoconjunctivitis, diabetes or Addison’s syndrome. Its effects are intense pain, photophobia and watering. With this condition it’s best to see the vet quickly, as it can worsen and cause the dog to lose the eye. Treatment uses medication, but if that doesn’t work, an operation is needed.
Glaucoma
There are two types: primary (hereditary) glaucoma, which is also present in humans but more painful in dogs. One of the main symptoms is loss of sight. It’s very important to see the vet as soon as possible, since fast-developing glaucoma could cause permanent blindness within hours.
Cataracts
This is a loss of transparency in the lens. There are two main types: congenital or juvenile (present in breeds such as the Poodle, Miniature Schnauzer or Cocker Spaniel) and acquired (caused by various diseases or by old age). Treatment involves surgery to remove the lens and, in some cases, replace it with an artificial one. If surgery isn’t possible, lifelong medication can be prescribed. With juvenile cataracts, an operation isn’t necessary, as they are reabsorbed spontaneously.
As you’ve seen, our pets are exposed to a wide range of eye conditions. Watching for symptoms and seeing the vet early is the best way to protect your dog’s sight and wellbeing.
