Dear Jacqui, and everyone else interested.
You can pick up relevant contacts and references for published works and
research on Human/Animal Interactions (of various kinds) from the
International Council for Anthro-zoology. They have a website, annual
conference for their members and publish a specific academic journal
exclusively on Human/Animal Interactions. The journal is called "Anthrozoos.
A Multidisciplinary Journal of The Interactions of People and Animals".
