I have a male american cocker spaniel and would like to breed him, does anyone have any info. how I can do that ?

Where do you live? If we know that we might be able to put you in touch with a reputable breeder or breed club. Have you asked your breeder for help?
Usually to be bred from your dog would need to be a show winner, unless you bought your own bitch and bred a litter yourself. Either way both dog and bitch will need to be eye tested under the BVA scheme for hereditary cataracts.
