since it is local and he is one year old call the owner to say you are interested and try setting up a playdate if vida is vicious then it isn't a good idea but if they are playing well then get him.. but if they both look interested and unsure set up another or a few more playdates, if the owner is truly interested in thier dog going to a good home i am sure they won't mind. I think having males and females together is perfectly fine!! but after breeding you might want to spay or neuter at least one of them.. unless you want to continue breeding after the first litter. i hope i helped..
