This essay is an exploratory study of the roles that non-human animals have played in diplomatic relations. Based on a few observations and case studies from the mid-twentieth century, it discusses how we may bridge the gap between the study of human and non-human animals in diplomatic history. It suggests that one way can be to focus on how humans have in practice used animals in diplomatic relations. In what contexts and capacities are non-human animals mentioned in diplomatic actors’ letters and diaries? In what shapes and settings do they appear in media coverage – written text and photographs – of diplomatic actors, and what significance has media ascribed to their presence? When do different sources describe non-human animals as an advantage or disadvantage for diplomatic relations? The essay surveys stories of the diplomatic use of animals ranging from the emotional effects of a diplomatic dog to the culinary consequences of keeping chickens for food.
