I agree with your mom, save up the money to finish health testing because being a good sheep herder means nothing without good health to pass on to the pups. This goes for the stud too. You're gonna have to have a lot of money set aside for care of the litter and mom. A good litter costs a lot and a disastrous litter costs more which I'm sure you and your mom probably already know. Before the breeding takes place you should also have a waiting list of people wanting pups from two proven parents, not just one.
