While we know that dogs evolved from wolves through a process of domestication, it remains unclear how this process may have affected dog cognitive development. Here we tested dog (N=44) and wolf (N=37) puppies, 5-18 weeks old, on a battery of temperament and cognition tasks. Dog puppies were more attracted to humans, read human gestures more skillfully and made more eye contact with humans than wolf puppies. The two species were similarly attracted to objects and performed similarly on… 
Early-Emerging and Highly-Heritable Sensitivity to Human Communication in Dogs
The results suggest that these social skills in dogs emerge early in development and are under strong genetic control.
Is cognition the secret to working dog success?
This review details recent work in the field of canine cognition, including how dogs have evolved socio-cognitive skills that mimic or, in some cases, rival even the authors' closest primate relatives.
Did Dog Domestication Contribute to Language Evolution?
This work hypothesizes about a parallel domestication of humans and dogs, and more specifically, about a positive effect of the authors' interaction with dogs on human self-domestication, and ultimately, on aspects of language evolution, through the mechanisms involved in the control of aggression.


The Domestication of Social Cognition in Dogs
It is found that wolves who were raised by humans do not show these same skills, whereas domestic dog puppies only a few weeks old, even those that have had little human contact, do show these skills.
Human-like social skills in dogs?
The effects of domestication and ontogeny on cognition in dogs and wolves
It is observed that wolves outperformed dogs in their ability to follow causal cues, suggesting that domestication altered specific skills relating to this domain, whereas developmental effects had surprisingly no influence.
Free-ranging dogs show age related plasticity in their ability to follow human pointing
Free-ranging dogs show a tendency to respond to human pointing gestures, with a certain level of behavioural plasticity that allows learning from ontogenic experience, which can provide deeper insights into differentiating between innate abilities and conditioning in dogs.
Ontogeny's impacts on human–dog communication
Human-Socialized Wolves Follow Diverse Human Gestures… And They May Not Be Alone.
It is demonstrated that human-socialized wolves are not only capable of responding to points made with the arm and hand, but are sensitive to a wide range of human gestures when given the opportunity to utilize such gestures in an object-choice task.
Explaining Dog Wolf Differences in Utilizing Human Pointing Gestures: Selection for Synergistic Shifts in the Development of Some Social Skills
Evidence is provided for the first time that socialised adult wolves are as successful in relying on distal momentary pointing as adult pet dogs, however, the delayed emergence of utilising human distal Momentary pointing in wolves shows that these wild canines react to a lesser degree to intensive socialisation in contrast to dogs, which are able to control agonistic behaviours and inhibition of actions in a food related task early in development.
