If you go onto cocker spaniel rescue Sussex there is one listed Gail Parsons 01903 725593 I think she is in Litlehampton. I got in touch with her 2 years ago but in the end we got Maggie from Dogs Trust Bridgend . The 2 journeys there were well worth it for us . This lady says to call between10am and 6 pm. Hope that you find a cocker soon.
