The information used from the interviews to address the research questions.

Research Question to Be Addressed:	Responses Used from Interviews Relating to the Following Elements of the Interview:	To Allow for Assessment of:
RQ1 “What information do clinical animal behaviourists identify and use in order to construct a perception of fear and frustration in dogs?”	“What is your definition and understanding of fear/frustration in dogs?”	To what extent respondents had similar or different theoretical perspectives for each of these emotions
	Questions relating to the behaviours used to indicate each emotional state and how they would recognise this state in a dog	How the presence of a given emotional state was determined in practice How respondents applied their theoretical understanding in practice and to what degree this was a scientifically rigorous process
RQ 2: “What processes are involved in how clinical animal behaviourists use this information to differentiate fear from frustration in practice?”	How they distinguish fear and frustration The features that must be present or absent to allow for this distinction and which features allow for each emotion to be ruled in or out of a case	The perceived importance of differentiating these states in practice and the quality of the processes used to achieve this
