There is a long list of reasons why dogs lose their sense of sight, partially or completely. For some dogs, a hereditary disease or congenital disorder may result in them being born blind. But there are also instances when a dog becomes blind later in life as a result of injury or illness. Blindness can affect dogs of any breed, sex, or age. Vision problems may also be an age-related health issue that many senior pets may have to contend with. Here are other conditions that are known to cause blindness in dogs:

• Cataracts - certain breeds are more prone to developing cataracts, which is characterized by cloudiness of the lens of the eyes.
• Glaucoma - there is buildup of pressure inside one or both eyes causing pain and pressure.
• Progressive Retinal Atrophy (PRA) - this is a congenital problem that causes gradual vision loss.
• Retinal detachment - there are many causes of retinal detachment, such as tumor, trauma, elevated blood pressure and inflammation among others.
• Corneal ulcers - if left without proper treatment and attention, there will be damage to the cornea thereby causing vision loss.

If you think your dog has eye problems or has trouble with his vision, be sure to bring your pet to your Aboite, IN vet as soon as possible. More information here: http://aboitevet.com/
