A new Lab in the family

Question
Hello,

Planning to move into a new home on rural farmland in June-July.  Two kids (M-F) ages 8, 6.
We want to get a Yellow Lab, probably a pup, female, spade.

First question: good choice?

Second: what to expect? (we are dog lovers and former dog owners, just not at present).

Third: how do solid hardwood floors fare with a dog?

Thanks.

Answer
Can't be too far wrong.  Most pups will not be spayed.  The vets like to wait until 6 months.  Glad you plan to take such a responsible step.  

I had grown up with dogs and had other ones before my first Lab.  I was not prepared.  Lab puppies can be much worse about biting and chewing, and very strong willed.  I strongly advise a crate.

You may want to skip the puppy stage.  It is much easier, and cheaper that way.
One of the best sources for dogs with a predictable personality is the rescue
dogs.  These are dogs that lost their home, but were taken into a foster home
to be retrained as necessary and placed in the right home for them.   You may
find a rescue near you starting at
