- How Many Footsteps Do Dogs Need to Determine the Direction of an Odour Trail?

Table 1 The number of times each dog in experiments 1–3 correctly determined the direction of a trail

Experiment 1 Experiment 2a Experiment 2b Experiment 3 DOG Track Jumbled track Control track Ground disturbance A 10* 6 5* 4 B 9* 4 5* 7 C 9* 3 5* 3 D 10* 5 5* 6 E 10* 5 5* 6 F 9* 6 5* 4

  In all cases 10 trials were offered to the dog with the exception of experiment 2b where only 5 trials per dog were used.

^* Indicates a significant (P < 0.025) level of performance as determined by a binomial test.
