As above, you need to decide what you want the dog to do before you decide on the breed. A couple of tips, don't let the kids play tug of war with the dog, it could lead to problems with retrieving/delivering game or a hard mouth. Don't let the kids kick or throw a ball for the dog to run after, or you won't be able to stop it running in when you're out shooting.
I've got two kids and two labs.
