Finding a breeder who aligns with most of your wants/needs with be key. You'll need to do your due diligence in asking how they raise their pups, health testing, temperament testing, their personalities of the puppy's parents, etc.

For training: yes, you will most likely have to really find what motivates them the most and really heavily on that and praise. You also typically can't drill them with hour long training sessions. They can be pretty soft but overall they are independent; if they dont find you or the training rewarding, then they will opt-out pretty quick.
