I give up!
Please don't give up .
Searching out this forum , registering and posting shows, in my opinion , you care what happens to your future addition . You can get so much advise not just now but after you get your puppy on behaviour training and future health.
Testing in cockers IS really important. As an incredibly popular breed the cocker has been profusely bred by unscrupulous breeders just for a fast buck and in order to make the most profit margin they don't follow the kennel club and British vet association guide lines for testing for these breed specific issues. which means that these eye conditions and kidney problems can pass through the lines so easily .
Even though the parents look healthy it dosnt mean the pups would be clear at all I'm afraid as I'm sure you know as you say you are still continuing your search . The kennel club do a link where you can be notified when the puppy list changes in your area and do list assured breeders and contact details . So you might like to make a few enquiries to see if they have any litter plans . Early bird catches the worm !
Good luck
