[H.P.]

If you want a pure bred, (nothing wrong with that) you need to make sure you find a reputable breeder, who breeds for the type of temperment you are looking for. Reputable breeders will usually have a waiting list for puppies, or check out breed rescues, these dogs will likely be in foster homes, have known temperments and some basic training. Check out the working breeds. It will still be important for you to go to training with your dog, so that the two of you learn to work together. You should be able to find a Saturday class, but you will need to practice with your dog daily, and make sure they get plenty of daily exercise, the type of dogs that you seem to be interested in need a lot of exercise and a constant reminder that they are not in charge by making them earn everything, which will be constant work for you - until it becomes habit for you. Not trying to discourage you at all, you seem to want a big active well behaved dog, and I just want you to know what that will require of you! Good luck, and keep us posted, this board is a wealth of information and support!
