I gave my suggestions. Check the health requirements, ensure she has been wormed, ensure you have buyers ready, Find a stud that matches your bitch - just because she or a potential stud have good pedigrees doesn't necessarily mean they are suited. Look at her carefully and also have a good look at the stud - do they complement each other - for instance, if she has a long back, does the stud have along back too? If so they pups may have back problems in the future. Does the stud have a fine head - is her head fine too - the pups may not have strong enough jaws to retrieve heavy game - like hares fro instance.
I didn't mean that you haven't thought about these things, these are suggestions that someone wishing to breed should do. I did not mean any offence.
