The animals of this group make friends with the experi- 

 menter in a short time. They learn to lead on a leash in 2 

 or 3 days, and in some cases on the first day. Although there 

 is a tendency for all dogs to withdraw when first approached, 

 this lethargic type does not become excited or hysterical.

After the training begins, they soon learn to run to the gate 

 when the experimenter approaches, and readily become will- 

 ing workers. The dogs of this group are not greatly disturbed 

 when first brought into the conditioned reflex laboratory. 

 There is no struggle against the harness and they appeal- 

 able to restrain themselves in every way. The average dogs 

 of the group take food after 2 day's training, and the con- 

 ditioning signal may be applied in 5 days (text-fig. 86). When 

 the training has progressed to the point where the condition- 

 ing signal is introduced, the animals go into the laboratory 

 ahead of the trainer and voluntarily take their places before 

 the food pan.
