Cataracts in Dogs

Three Minutes Apr 13, 2022

What are Cataracts?

Dogs with cataracts will show opacity in the lens of the eye. Cataracts often result in your dog experiencing blurry vision. Smaller cataracts will not often result in severe vision loss; however, as the cataracts become thicker, your dog may become completely blind in one or both eyes. You may or may not notice cataracts immediately; however, the moment you begin to notice them you should contact your veterinarian.

Breeds at the Highest Risk of Developing Cataracts

Dogs of all breeds, genders and ages may develop cataracts; however, this condition is most commonly found in the following breeds:


Symptoms of cataracts include:

  • Cloudy eyes
  • Apparent blurry vision
  • Bluish-gray eyes

If your dog has a diabetes-related cataract, other symptoms may also appear including:

  • Weight loss
  • Increased urination
  • Increased thirst

Causes of Cataracts

Cataracts may be caused by a number of factors including:

  • Age
  • Diabetes
  • Disease
  • Trauma
  • Electric shock
  • Exposure to toxins
  • Hypocalcemia

Genetics may often be the common cause of cataracts, though. Cataracts may even be present at birth. Dogs between one and three years of age are most commonly affected.

How To Treat Cataracts In Dogs

Cataracts are treated via surgery. If surgery is recommended by your veterinarian, ensure you have the surgery performed as soon as possible. Cataracts are known as a progressive condition and symptoms worsen as time progresses.

In the surgical procedure, a veterinary ophthalmologist will surgically remove the lens of the eye and replace it with a plastic lens. Cataract surgery is highly successful if your dog is determined to be a good candidate. Following surgery, your dog will be required to wear a protective collar until the eye heals. Eye drops several times per day for several weeks is also necessary.
