Welcome to the club.
Great wiht kids.
High energy so she'll be needing walks and they love to play always.
Mouthy means a good retreiver and they tend to nip alot in play so have a lot of chew toys handy -those milk teeth are sharp -she is not biting you just being a lab
Crate train -labs are very anal so make sure the crate is not too large.
most all my labs house train fast - do not paper train
Careful with food as they tend to pick up weight
I am on the list waiting for my second one
