Wolves as pets and working animals
Generally speaking, on the basis of their experience, tame wolves are strictly "one-man dogs". They may be confiding and playful with the man who raised them, or even with his whole family, if fed and cared for by them, but they are suspicious and timid in the presence of strangers. They invariably retain certain reactions of wolf nature, as for instance, an incorrigible desire to kill chickens or other small livestock whenever opportunity arises.
Inequity aversion in animals
Wolves ("Canis lupus") are highly social animals that cooperate in hunting, breeding and defending their territories. Essler, Marshall-Pescini, and Range set up an experiment with nine wolves and ten pack-living dogs to investigate if domestication was the reason dogs show a primitive form of inequity aversion.
The animals had to press a buzzer to receive a reward, which was either equal or inferior to the reward of a partner performing the same action in an adjacent enclosure.
The wolves stopped pressing the buzzer once they observed their partner got a better reward for the same action.
In the conditions without receiving a reward, wolves completed fewer tasks when there was a partner who did get rewarded than when there was no partner at all. Taking the social hierarchy into account, dominant wolves reacted strongly to a subordinate being rewarded when they were not. Given that the results for pack-living dogs were very similar, the researchers concluded that the common ancestor of wolves and dogs likely already was inequity averse, and that domestication is not a factor for this behavior in dogs.
