Meg wasn't at all interested in balls until we introduced two on the advice of mark at top barks. Total transformation, she doesn't really want to retrieve them but just loves the chase. If she starts to wander off we just say ball,meg and she comes flying bàck. We live about an hour from mark but had a two hours session with him one Saturday when meg was about 9 months old and it was the best money I ever spent in terms of her training. He just helped us identify what interested her. Whatever you decide to do, good luck, cockers are incredibly intelligent dogs and you will get thère it is just finding out what suits you all.
