Hi Stone,
MRDysplasia: This is an eye condition with which the pup is born ( congenital ). It would either be blind soon after its eyes open or noticeable up to 6 months when it starts walking into objects, although strangely enough not always blind.
Looking through an ophthalmoscope would see grey streaks folds and ridges ( like crumpled up paper )Also have grey patches like rosettes. If you shine a light into the eye the reflection is brighter than normal ( Tapetum ).
Hereditary condition caused by an autosomal recessive gene . What this means is that both parents are carriers and the pups inherit this gene from both the stud and the dam.They may both be OK but are both carriers.
There is no treatment.Breeding from them is a definite no no.
