Dogs that are trained to a rigid discipline, 1916 (c).

Armies used dogs in various capacities. They were trained to carry messages and medical supplies, act as sentries, and were used in mine detection and seeking out casualties. The threat of snipers made it hard for people to carry messages over long distances. Dogs presented a smaller target and were able to travel faster than human messengers. One of 193 British and Allied Official photographs taken on the Western Front during World War One. Mounted on card, some with their original captions.
