Tell me first,
How much time do you want to spend a day exercising?
Do you want a steady, reliable, gentle, cushion for the kids type dog, or a fun, busy, fetch the ball, run around the garden being 'trained' over jumps by the kids type dog?
Are you prepared to commit to some kind of weekly activity, obedience, agility, flyball etc (would be great with the older kids)?
How much time a day do you have to groom?
How much time a day do you have to train?
Do you want a kitchen/downstairs 'in your basket' dog, or a sofa/bedroom, I would like to be with you all the time dog?
How important is it that you dog is (or appears to be) very well behaved?
No right or wrong answers, just be honest
