Whereas studies in comparative cognition normally invoke ecology and social organization to account for differences in social behaviour and cognition across species, dog–wolf differences have so far been explained mostly as a result of direct human selection for desirable traits ( e.g. , tameness, ...
Each walker was asked to fill in several questionaires, including the NEO-FFI personality test, an attitude-towards wolves and dogs scale, and an animal personality rating. A lot of differences in performances of human-dog and human-wolf dyads were found. Results indicate that walking with ...
We investigated the spontaneous tendency of dog puppies, kittens and wolf pups to match their behaviour to actions demonstrated by a human, in the absence of food reward. Based on dogs’ inherent sociality and domestication history, we predicted that the tendency to match human actions is more ...
In this study we successfully applied genome-wide procedures to reconstruct the history of the Czechoslovakian Wolfdog, assess individual wolf ancestry proportions and, thanks to the availability of a well-annotated reference genome, identify possible candidate genes for wolf-like and dog-like phenotypi...
Methods: We documented the timing of completed eruption of permanent dentition into occlusion (dental maturity) and the timing of growth plate closure at the proximal humerus (skeletal maturity) in ontogenetic series of wolves and 15 domestic dog breeds. Data for 137 domestic dog and 64 wolf ...
partially reverting the effects of domestication [1]. A prominent example of such a tendency is represented by the growing popularity of commercialized wolfdog breeds, such as the Saarloos Wolfdog, the Lupo Italiano, the Kunming Wolfdog, the American Wolfdog and the Czechoslovakian Wolfdog, which...
To determine behavioral differences between the breeds, the researchers enlisted the assistance of 56 dog volunteers. Each was trained to tip over a cover concealing food. Those that passed the test (77 percent of them) moved on to the next stage. In the second part of the experiment, the ...
Following massive persecution and eradication, strict legal protection facilitated a successful reestablishment of wolf packs in Germany, which has been ongoing since 2000. Here, we describe this recolonization process by mitochondrial DNA control-region
In European ecosystems, scavengers competing for wolf kill remnants typically include meso- and large-carnivores such as the red fox (Vulpes vulpes, Bassi et al.2018), raccoon dog (Nyctereutes procyonoides, Selva et al.2005), wolverine (Gulo gulo, Nordli et al.2024), brown bear (Ursus ar...
In the months since we first sat on a patch of grass and rubbed her dog’s belly while she teased me for taking milk with my coffee, I have made a fool of myself more than once. I’ve told her that I want to be her partner, that I love her, and that when I’m around her...
