Update on Frank Smith & Patch the Dog
The most famous Bomber Command pet is Guy Gibson’s Labrador, Nigger. However, other dogs appear in photos of Bomber Command aircrew, some of whom traveled with their owners on bombing sorties.
Frank Smith was with 97 Squadron at the end of the war, flying as a rear gunner with a pilot named Harrison. The celebratory photograph below may either have been taken when they finished their tour or when the war ended.

Patch the dog appears with Frank (they seem to have been inseparable) in a number of photos. It is thought that Patch was brought back from Belgium after the war ended and that the crew hid him on the plane in order to get him back.
The photograph below is one of the best informal photos we have seen of the quiet life back at base. Patch appears on the far left, held safely by Frank.
With many thanks to Margaret and Jeffrey Bossons.
