I have three small dogs.  Another fact about dogs is that the dog and the gray wolf are sister taxa 
The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct.

Evolution of the wolf
The evolution of the wolf occurred over a geologic time scale of 800 thousand years, transforming the first Middle Pleistocene wolf specimen that is recognized as being morphologically similar to "Canis lupus" into today's dog, dingo and gray wolf. Ecological factors including habitat type, climate, prey specialization and predatory competition has greatly influenced the wolf's genetic population structure and cranio-dental plasticity. Wolves went through a population bottleneck 20,000 years before present (YBP), which indicates that many wolf populations had gone extinct at a time that coincided with the Last Glacial Maximum and the expansion of modern humans worldwide with their technology for capturing large game.
Origin of the domestic dog
The origin of the domestic dog is not clear. The domestic dog is a member of the genus "Canis", which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The closest living relative of the dog is the extant gray wolf and there is no evidence of any other canine contributing to its genetic lineage. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated. The archaeological record shows the first undisputed dog remains buried beside humans 14,700 years ago, with disputed remains occurring 36,000 years ago.
Gray wolf
The gray wolf ("Canis lupus"), also known as the timber wolf or western wolf, is a canine native to the wilderness and remote areas of Eurasia and North America. It is the largest extant member of its family, with males averaging and females . Like the red wolf, it is distinguished from other "Canis" species by its larger size and less pointed features, particularly on the ears and muzzle. Its winter fur is long and bushy and predominantly a mottled gray in color, although nearly pure white, red, and brown to black also occur. "Mammal Species of the World" (3rd ed., 2005), a standard reference work in zoology, recognises 38 subspecies of "C. lupus"..Gray wolfs are pack hunters.
Dog
The domestic dog ("Canis lupus familiaris" or "Canis familiaris") is a member of the genus "Canis" (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Their long association with humans has led dogs to be uniquely attuned to human behavior and they are able to thrive on a starch-rich diet that would be inadequate for other canid species.
Red wolf
The red wolf ("Canis rufus" or "Canis lupus rufus"), also known as the Florida black wolf or Mississippi Valley wolf, is a canid of unresolved taxonomic identity native to the eastern United States. It is generally, morphologically, an intermediate between the coyote and gray wolf, and is of a reddish, tawny color. The Red Wolf is a federally listed endangered species of the United States, and is protected by law. It has been listed by IUCN as a critically endangered species since 1996. It is considered the rarest species of wolf and is one of the five most endangered species of wolf in the world.
Coyote
The coyote ("Canis latrans"); from Nahuatl ) is a canine native to North America. It is smaller than its close relative, the gray wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia, though it is larger and more predatory, and is sometimes called the "American jackal" by zoologists. The coyote is listed as least concern by the International Union for Conservation of Nature due to its wide distribution and abundance throughout North America, southwards through Mexico, and into Central America.
Coywolf
Coywolf (sometimes called woyote) is an informal term for a canid hybrid descended from coyotes and gray wolves. Hybridization between the two species is facilitated by the fact that they diverged relatively recently (around 55,000–117,000 years ago). Genomic studies indicate that nearly all North American gray wolf populations possess some degree of admixture with coyotes following a geographic cline, with the lowest levels occurring in Alaska, but the highest in Ontario and Quebec as well as Atlantic Canada. Hybrids of any combination tend to be larger than coyotes but smaller than wolves, they show behaviors intermediate between coyotes and the other parent's species.

That's pretty interesting.  I used to have a small dog, a pug when I was younger.

Love pugs!  Another thing is that dogs and their long association with humans has led them to be uniquely attuned to human behavior

Dog behavior
Dog behavior is the internally coordinated responses of individuals or groups of domestic dogs to internal and external stimuli. It has been shaped by millennia of contact with humans and their lifestyles. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans and they are uniquely attuned to their behaviors. Behavioral scientists have uncovered a wide range of social-cognitive abilities in the domestic dog  The origin of the domestic dog ("Canis lupus familiaris" or "Canis familiaris") is not clear.
Psychology
Psychology is the science of behavior and mind, including conscious and unconscious phenomena, as well as thought. It is an academic discipline of immense scope and diverse interests that, when taken together, seek an understanding of the emergent properties of brains, and all the variety of epiphenomena they manifest. As a social science it aims to understand individuals and groups by establishing general principles and researching specific cases. In this field, a professional or researcher is called a psychologist and can be classified as a social, behavioral, or cognitive scientist. Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the physiological and biological processes that underlie cognitive functions and behaviors.
Pug
The Pug is a breed of dog with physically distinctive features of a wrinkly, short-muzzled face, and curled tail. The breed has a fine, glossy coat that comes in a variety of colours, most often fawn or black, and a compact square body with well-developed muscles. Pugs were brought from China to Europe in the sixteenth century and were popularized in Western Europe by the House of Orange of the Netherlands, and the House of Stuart. In the United Kingdom, in the nineteenth century, Queen Victoria developed a passion for pugs which she passed on to other members of the Royal family. Pugs are known for being sociable and gentle companion dogs.

Pedigree Dogs Exposed: Three Years On
Pedigree Dogs Exposed: Three Years On is a 2012 follow-up to the 2008 BBC One documentary, "Pedigree Dogs Exposed" ("PDE"). While this second programme looks at the positive changes made since the original film, it focuses on investigating areas of continuing concern. The programme concluded that it was time to call a halt to suffering created by breeders. It states that as long as The Kennel Club (KC) tolerated human whim leading to dogs that cannot run, breathe, or see freely, dogs would continue to suffer, but featured that, in fact, KC would continue in the vein, suggesting that the organisation has a conflict of interest in juggling its commitments to breeders and to dogs – when the interest of dogs does not match up with that of breeders, the dogs suffer.
Human behavior
Human behavior is the responses of individuals or groups of humans to internal and external stimuli. It refers to the array of every physical action and observable emotion associated with individuals, as well as the human race. While specific traits of one's personality and temperament may be more consistent, other behaviors will change as one moves from birth through adulthood. In addition to being dictated by age and genetics, behavior, driven in part by thoughts and feelings, is an insight into individual psyche, revealing among other things attitudes and values. Social behavior, a subset of human behavior, study the considerable influence of social interaction and culture.

I've always wondered about that.  I've always sensed that dogs know more about us than it seems.
