First of buddy you need to gain knowledge on working dogs and that's not done over night second if you do get a well bred dog you will need to graft it a good few seasons and work at it and even then if it does work out ask yourself are you breeding better than what's already out there is the other dog going improve what you already have by breeding with it and then there's finding good working homes for your pups which is a job in it self if I was you buddy I would read as much info as I could books internet YouTube ect try out get out with someone decent to show you the ropes and do that
