I feel it is very important to be prepared. It may be that everything works out great and it is a wonderful match. On the other hand, if the puppy arrives and things are not working out so great, it is really important to have a plan for what you will do. This is especially important since the breeder is not local.
Are you equipped to separate your household if neccessary? Have you found a local trainer and behaviorist you can work with if issues arise?
These are things best thought about before an issue arises rather than just hoping for the best. Then if something does happen, you don't have deal with these things when your emotions are running high.
