i haven't bred yet, as I'm still researching. Do you have breeder/mentor who can assist you with what to expect when it comes to studding including but not limited to possible behavior changes, contracts, testing, evaluate your potential stud, etc? The Breeding Forum may have more information regarding this in comparison to the General section(use the search function...most questions have already been answered). I find the AKC website has very good information as well and I've provided the link for you. Welcome to YT btw!!!
