  1. The performances of the three dogs in a two-alternative forced-choice experiment with thermal stimulation. Stimulus temperature was 11–13 °C higher than ambient temperature. The circular stimulus patches were 102 mm in diameter and had to be detected from a distance of at least 1.6 m, i.e. they subtended a solid angle of about 3.7 degrees. Their centres where at maximum 16 degrees apart. In all experiments, the dog handler did not know the answer and no other person could influence the dog.
