Canadian troops in camp at Salisbury Plain posing with their regimental pet, a black bear. There is no hard fast evidence to suggest so in the caption but it is possible that this is Winnie, the bear smuggled to Britain by Lt. Harry Colebourn of The Fort Garry Horse, a Canadian cavalry regiment en route to the Western Front. The bear was left at London Zoo where she became very popular with visitors, including Christopher Robin Milne, son of A. A. Milne, who would go on to write his Winnie-the-Pooh stories based on the animal.
