Dog’s Cloudy Eyes May Be Normal Aging Change, Not Cataracts

Dogs are very sensitive animals that require a lot of attention and respond well to praise and affection; for this reason, they are not a good choice for those who spend a lot of time away from home and rarely venture outside for recreation. Ann Lillie/Shutterstock

Q: When Toto, my 10-year-old terrier, looks at me, his eyes appear cloudy. At last week’s wellness exam, his veterinarian said his eyes are healthy and he has no cataracts or other problems. So why do his eyes reflect a cloudy white-blue-gray haze?

A: It sounds like Toto has a condition called nuclear sclerosis, which is not a disease but a normal consequence of aging that starts in dogs around age 7.
