Longtail

[Big D]

Harold - Thee is no way my 15 minutes with the Vet and on line will stand up to your training and experience, but here is what I found:

"The condition is differentiated from a cataract by its appearance and by shining a penlight into the eye. With nuclear sclerosis, a reflection from the tapetum will be seen, while a cataract will block reflection. There is no treatment for this condition currently."

[Harold Pickens]

Actually, we are all on the same page here (you, me, and your vet). Nuclear sclerosis will occur in all of us -- dogs or humans. It is a clouding of the lens that occurs in most all dogs by age 7, and in humans in our 60's. I tell people that if they die before before they develop nuclear sclerotic cataracts, they are dieing young. The vets sometime describe this differently, but any change to the clarity of the lens is by definition a cataract---have discussed this with my brother who is a Vet also. Still, I bet your Daisy has many productive years left, cataract surgery commonly not done on dogs, just not necessary . Hunted my setters as long as they could physically, 12-14 yrs old.
Hope you are having a great season
