A Czechoslovakian Wolfdog. The domestic dog (Canis familiaris) is a domesticated species of the gray wolf (Canis lupus), along with the dingo (Canis lupus dingo).Therefore, crosses between these species are biologically unremarkable and not a hybridization in the same sense as an interbreeding between different species of Canidae.
Ancient DNA from the remains of these dogs indicates that they belong to the same genetic lineage as modern Arctic dogs, and that this lineage gave rise to the earliest native American dogs. Since the earliest native American dogs, multiple, genetically different lineages of dogs were introduced by the Thule people and European settlers. The ...

Although the evolution of humans increases the level of intelligence, the same may not be observed in other animals, especially animals which have great dependence to humans – for example, dogs. While different breeds of modern dogs possess different brain capacity and intelligence, in general, compared to the wolf, the dog's problem-solving ...
The Paleolithic dog was smaller than the Pleistocene wolf (Canis c.f. lupus) [1] and the extant grey wolf (Canis lupus), with a skull size that indicates a dog similar in size to the modern large dog breeds. The Paleolithic dog had a mean body mass of 36–37 kg (79–82 lb) compared to Pleistocene wolf 42–44 kg (93–97 lb) and recent ...
The addition of domestic dog genes may have played a minor role in facilitating the eastern hybrids' adaptability to survive in human-developed areas. [ 18 ] The four-in-one hybrid theory was further explored in 2014, when Monzón and his team reanalyzed the tissue and SNP samples taken from 425 eastern coyotes to determine the degree of wolf ...
Ordinary pet food is inadequate, as an adult wolf needs 1–2.5 kg (2–5 lbs) of meat daily along with bones, skin and fur to meet its nutritional requirements. Wolves may defend their food against people, and react violently to people trying to remove it. [2] The exercise needs of a wolf exceed the average dog's demand.
Dog communication is the transfer of information between dogs, as well as between dogs and humans. [136] Communication behaviors of dogs include eye gaze, facial expression, [ 137 ] [ 138 ] vocalization, body posture (including movements of bodies and limbs), and gustatory communication (scents, pheromones, and taste).
