“…Given their co-evolution with humans1917 and capabilities to respond to human cues17181956, they are an interesting species worth studying to investigate how similar traits may have arisen via evolution. One brain network that has been implicated in cognition in general (as well as in social cognition)5758 is the default mode network.…”

“…For example, in the object choice task, dogs need to attend to a person’s point and/or gaze to successfully locate a hidden object. Of note, not only do dogs display joint attention with humans and respond to human pointing and gesturing but they do so better than nonhuman primates making them an excellent animal model for human social cognition9171819. From an evolutionary perspective, the canine advantage is either due to the domestication of dogs (from their predecessors, wolves), their close contact with humans during their daily lives, or is a residual mechanism present before the lineages split 97 million years ago.…”

Diffusion tensor imaging (DTI) provides us an insight into the micro-architecture of white-matter tracts in the brain. This method has proved promising in understanding and investigating the neuronal tracts and structural connectivity between the brain regions in primates as well as rodents. The close evolutionary relationship between canines and humans may have spawned a unique bond in regard to social cognition rendering them useful as an animal model in translational research. In this study, we acquired diffusion data from anaesthetized dogs and created a DTI-based atlas for a canine model which could be used to investigate various white matter diseases. We illustrate the application of this atlas by calculating DTI tractography based structural connectivity between the anterior cingulate cortex (ACC) and posterior cingulate cortex (PCC) regions of the default mode network (DMN) in dogs. White matter connectivity was investigated to provide structural basis for the functional dissociation observed between the anterior and posterior parts of DMN. A comparison of the integrity of long range structural connections (such as in the DMN) between dogs and humans is likely to provide us with new perspectives on the neural basis of the evolution of cognitive functions.

“…Barrera, Jakovcevic, Elgier, Mustaca, and Bentosela (2010) showed that, in a simple sociability test, shelter dogs remained closer to passive unknown humans than did pet dogs, but also presented more fearappeasement behaviors. Laboratory-reared dogs and dogs living in shelters have also been found to show an impaired ability to follow subtle human gestural cues to a target in object choice tasks (Lazarowski & Dorman, 2015;Udell, Dorey, & Wynne, 2008;Udell, Dorey, & Wynne, 2010b), although this effect can often be reversed with additional training (Udell et al, 2010b). Shelter dogs also exhibit a faster extinction of gaze toward a human face in the presence of out-of-reach food than do pet dogs (Barrera et al, 2010).…”

Sociability, defined as the tendency to approach and interact with unfamiliar people, has been found to modulate some communicative responses in domestic dogs, including gaze behavior toward the human face. The objective of this study was to compare sociability and gaze behavior in pet domestic dogs and in human-socialized captive wolves in order to identify the relative influence of domestication and learning in the development of the dog-human bond. In Experiment 1, we assessed the approach behavior and social tendencies of dogs and wolves to a familiar and an unfamiliar person. In Experiment 2, we compared the animal's duration of gaze toward a person's face in the presence of food, which the animals could see but not access. Dogs showed higher levels of interspecific sociability than wolves in all conditions, including those where attention was unavailable. In addition, dogs gazed longer at the person's face than wolves in the presence of out-of-reach food. The potential contributions of domestication, associative learning, and experiences during ontogeny to prosocial behavior toward humans are discussed.

“…The test could potentially be used in veterinary behaviour contexts to monitor cognitive changes in ageing dogs, utilizing a simple binary measure of success. (Halmágyi 2010;Lazarowski & Dorman 2015;Szabó et al 2016;Wallis et al 2014). For these reasons, the use of existing paradigms is limited to laboratory settings, and provides little benefit to the non-laboratory canine population.…”

Decline in the visuo-spatial memory domain may be an early marker for cognitive decline and has a relevant impact on animal welfare. Current research on visuo-spatial memory in family dogs is often limited byfactors such as the need of extensive pre-training, limited attention to co-occurring medical conditions, a focus on laboratory dogs, or low sample size. Therefore, we aimed to develop a test that relies on visuospatialshort-term memory, may be performed in a short time, and does not require explicit training. We tested a large sample of young and old dogs, finding that young dogs were more likely to perform correctly, although performance decreased with consecutive trials in both age groups. However, groups did not vary in the severity of mistakes. This task represents the first measure of dogs’ age-related decline of short-term spatial memory that does not require explicit training. The test could potentially be used in veterinary behaviour contexts to monitor cognitive changes in ageing dogs, utilizing a simple binary measure ofsuccess.
