Hi, I agree with everything Jackie and John have said, but also remember it is essential to have both of you dogs eyes tested, and to find out the current eye status ( and the status at the time of mating, of course) of both your dogs and bitches parents, as well as the eye status of as many grandparent as possible, but especially the common grandfather.
This being Cockers we are talking about, query temperaments of parents/grandparents, if at all possible. One of the Cocker specialists on the site (are you out there, Jane?) might be able to point you in the right direction is you give her details of your dogs?
