ive got a great lab that has been the perfect family dog. he is getting older now and we are thinking of getting a puppy out of his same bloodlines(foster is neutered). he is a registered dog and we have a history of his lineage but no kennel names or contact info. is there a way to track this info down?

the reason we want to get a puppy relativly soon is we thought maybe the puppy would pick up on some of fosters behaiviors and it would make training a little easier. is this going to be the case? if not what would you recomend?

The easiest thing to do is to begin with a Google search to get your feet wet. I wouldn't stop there, though. You can try contacting the AKC to see who the breeder and owners were. If he is a hunting dog, there's likely a trial connection, so you can also contact field trialers in your area. Most trialers can recite blood lines better than their own lineage!
