This paper explores the process of becoming within the relation between a human and a horse, and seeks to reimagine pedagogy as a relational process of "becoming-animal." In order to emphasise the relational space between a horse and a human, I begin with an experimental style of writing that traces specific moments between an actual relation between a horse and myself. Considering the relation as a singularity in this way acts as a method through which the pedagogical relation can be explored and new pedagogical images can be suggested. I then move onto to discuss Rosi Braidotti's post-humanist ideas on becoming and link these to the ideas of the "event" and of "beginnings" within the educational theory of Gert Biesta, drawing out two lines of thought. One line follows Braidotti's work on becoming-animal, and the other Paul Patton's work on the nuances of power relations between humans and horses. In conclusion, I discuss how this figuration of a halter and a lead rope in the human-horse relation helps to think pedagogy as rooted in becoming-animal and how this contributes to the development of new imaginaries of becoming.
