Does my dog have cateracts? Many dog owners of older dogs think their pet has developed cataracts because they notice that the lens of the eye has taken on a greyish bluish colour at its centre. Any such changes in the eye should ALWAYS be checked out by the Vet but, in fact, in the vast majority of cases the condition is not a cataract – it is a much less serious condition called nuclear sclerosis, which is a normal ageing process in dogs.
A simple test at the vets can confirm this. No treatment is needed for nuclear sclerosis and vision is not significantly impaired.
