Dogs and owners entered a waiting room within the laboratory suite together, and the owners were given a brief explanation by the experimenter of what to expect regarding the amount of time the session would take, instructions for how to behave in the different phases of the study, and the purpose of the study. The predictions were not explained to the owners until after the session ended. Then, dogs and owners were led into the 3 5.5 m

testing room for a 10-minute exposure phase. In total, dogs spent approximately 20-30 minutes in the laboratory suite, of which 13 minutes were in the testing room. Although Broom et al. (2009) had a 5-hour exposure period in their pig study, 5 hours of exposure was not feasible for a large number of dogs whose owners were required to be present throughout the session. Personal communication with Broom (14 July 2011) also suggested that a shorter period of exposure was likely to be sufficient.
