Kevin is right, GSP are usually quite thin, but that is excessive. The black one is probably part GSP, but they GSP are either liver (all brown) or liver and white (ticked or patched) so the black one must have something else in there. GSP's are also a little stubborn and roaming. My dad trained a few of them when I was little and they're notorious for wandering out of their boundaries.
I also agree with opening day wander-off's. My husband always cusses about hunters with under-trained dogs. He's had his birds stolen by other hunter's dogs because they let their dog run too free and don't have a solid recall.
Poor puppies look rough.
