Why do you want to breed her...does she have titles of any kind? even a temeperment test like CGC or anything like that over there? IS she the perfect Staff..according to standard? has she been judged by a bias person..ie judge..saying she is perfect and will better the bloodline of the staff? HAs she been health certified? or OFa'd cerifiied? hips/joints check? by a reputable vet or specialist in these areas?
Is she hyper/shy or uneven tempered at people or other dogs...I'm talking strange dogs not those in your friendly group? These are things you need to consider before you can even start to do any breeding. Once you have pups do you have a list of buyers/takers already set up for the minimum (that could be 5 pups) amount of pups she might produce? You'll need to check and make sure the stud is also met all these requirements also before you breed with him, she is only half of the genes your putting into the gene pool. Since she can be in heat for 3 weeks, the stud and her will figure it all out, are you ready in case they fight for the first time? Take pups back if adopter doesn't want it anymore?and to the vet for their first check ups and keep them and fed them until they are at least 8 weeks old? Start socializing and potty training?
There are so many out there like has been stated...every dog you give or sell kills one at a shelter.
I would research a bit more please...you can look up when the best time is.

I don't mean to make you mad, but I train dogs from bad breedings and I don't think they needed to be that way had ppl taken time to think before acting. Please reconsider..and spay your dog and enjoy
