Peggy doesn't want to think of worse, quite honestly. Bastogne and those winters had been bad enough, not something she wants to go back to, but at least they have a purpose here. She tugs on the mittens and already is on her way out the door, ready for Riza to lead. "Where would he go, if he had to run on instinct?" she asks, knowing that they can't track him like he's a person, but everyone has their instinctual reactions that they follow.

Dogs are no different from humans in that, so Peggy knows that they'll have a good shot of at least knowing where to start.
