It has proven hard to immediately notice dog blindness in its initial stages since dogs are better equipped to deal with blindness as compared to man. Few cases of sudden dog blindness are recorded, and it’s hard for the dog to adjust to especially Suddenly Acquired Retinal Degeneration (SARDS).

Sudden dog blindness has adverse effects since the dog is plunged into darkness without warning. Nervous breakdown and depression are among such results. The owner also has his share of impact in making quick adjustments to assist the dog in adjusting to his new condition.

Further symptoms of Glaucoma include slow response to bright light, bloodshot eyes, and pupil dilation. It can be treated medically and surgically.

Inherited causes of dog blindness include genetic conditions that run in the dog’s family. The standard genetic causes of dog blindness are Suddenly Acquired Retinal Degeneration(SARDS) and Progressive Retinal Atrophy(PTA). SARDS is a condition which affects the retina and prevents it from functioning. It is commonly observed in dogs between 6 to 14 years. Read about bullmastiff lab Mix – Mastador

It is the primary cause of sudden blindness in dogs with dogs going completely blind within four weeks after it is noticed. The chances of successfully treating SARDS are narrow being that it occurs suddenly and the cost involved may be too high. PTA is another genetic condition which causes the degeneration of the retina. It is more common in certain types of breeds such as poodles, schnauzers, and collies.

Some common indicators of PTA include a decrease in the night vision since it will strain to focus. Unlike its counterpart, this condition develops gradually throughout less than one and a half years. This is an agent of gradual dog blindness. This degenerate condition has no known cure but only supplements to slow the rate of degeneration.

Finally, injuries can cause dog blindness if they damage the eye to a great extent. Some common injuries are severe cuts, scratches, and scrapes on the eyes. Minor cases can be corrected using surgery, but extreme injuries will lead the dog to lose sight permanently.

The owner should avail fresh food to the dog rich in vitamins and other nutrients such as lutein. The nutrients will enhance the dog’s eye health by nourishing it. Another preventive measure is a regular examination or checks up by the veterinary on the dog’s eyes.

Especially to notice any change in the appearance of the eyes together with any behavioral changes. SARDS has been linked with the release of a steroid-like substance by the dog’s body glands. This steroid-like substance interferes with the dog’s sex hormones which lead to adrenal diseases causing SARDS.

The owner should allow the dog to maintain his sex hormones to reduce the likelihood of obtaining SARDS. Finally, the owner should prevent obesity in the dog by keeping a low- carbohydrate diet to reduce the chances of the dog acquiring diabetes which causes dog blindness as a secondary symptom.

Dogs may not rely on their sense of sight as much as we humans do, but a loss of this sense will affect the dog’s healthy living. This calls for the precautionary measure to be taken to enable a dog to keep his sight for a long while.
