Hello and welcome. Alot of people are very knowledgable on these such things here.
Is this your first dog?
Do you have time for a puppy?
Planning on getting from a breeder? or would you consider a slightly older dog from a rescue (may be good if you don't have the time to let a new puppy out every 2 - 3 hours)
I'll let the experts take over. Like trinitie said its important to be knowledgable about the breed and ask as many questions as possible.
