I must admit, what the bitches were fed was not top of my list of priorities when looking for a puppy
Those are the types of questions that should be asked once you are satisified that both dogs are of a suitable temperament & type to be bred from and have had the recommended health tests. To suggest that health testing & temperament shouldn't be a priority is very irresponsible. You will find that the majority of cocker puppies will go to pet homes - it's not just people who show or breed who deserve a healthy puppy so you cannot use the fact that you just breed for the pet market as an excuse not to eye test. I'd run a mile from a breeder like you
Mind you, I do have an entire male here (both testicles present & correct) who I had hoped to breed from but had deemed him unsuitable due to the fact that he is small, nervous & has a possible hereditary problem. Now I know that those aren't good enough reasons NOT to breed from him, I think I'll nip across to the park later and find him a girlfriend. I have a difficult choice ahead however - a litter of mediocre cockers with probable health problems (its okay though, they will just be pets!) or, if there are no cockers about, he could just contribute to yet another litter of much wanted mongrels
