One of the most common misconceptions regarding aging dogs’ eyes is that a cloudy appearance means the dog has cataracts. The outer surface of a dog’s lenses thickens over the life of the dog and at some point, it will be thick enough to actually block some of the light from reaching the retina and cause a reflection that we see as greyness or cloudiness of the eye.
Typically dogs can still see normally with this condition, called nuclear sclerosis or lenticular sclerosis, as long as there is adequate light. Cataracts do occur in dogs, however, and an exam by your veterinarian can determine what condition your dog has.
