Signs of Cataracts in Dogs

Dogs develop cataracts due to age. Cataracts can rob a dog of his vision and reduce his quality of life. If the dog is employed as a guard or police animal, blindness will be a more serious problem than it would be in a companion animal. Whether the dog is a pet or a work animal, cataracts should be treated by a veterinarian.

Blue or Icy Eyes--Primary Symptom

The primary symptom of cataracts in dogs is the eye lens becomes blue or icy. There are two types of cataracts in dogs: mature and immature. If the dog's lenses are gray, this is normal due to aging and does not interfere with the animal's vision, according to Peteducation.net.

Loss of Vision

The only other outward symptom is a decrease in the dog's visual acuity. Cataracts always are accompanied by the eye lens changing color, but if it is a small spot, it may be overlookd by an owner. Any breed of dog can develop cataracts, but certain breeds like retrievers are more likely to develop this condition, according to Professorshouse.com.

Immature and Mature Canine Cataracts

An immature cataract is growing and has not robbed the dog of its sight. A mature cataract covers the entire lens, and an immature cataract covers part of the lens. Immature cataracts usually develop into mature cataracts.

Do Cataracts Occur in One or Both Eyes?

Dogs can suffer cataracts in either eye, or they can suffer cataracts in both eyes simultaneously. Taking the dog to a vet can determine if there are any other underlying health problems that contributed to the cataract and help the vet decide on the best course of treatment.

Complications

Golden and Labrador retrievers are more likely to suffer from cataracts than other breeds. Conditions such as diabetes also can increase a dog's risk. A vet will consider the dog's health and aggressiveness before deciding whether the dog is a good candidate for this type of surgery.
