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.
Dingo (taxon)
The taxon dingo refers to the native dog found in Australia but may at times also refer to some similar dogs native to peninsular and island southeast Asia and neighboring regions, such as the New Guinea singing dog. The genetic evidence indicates that the "dingo" clade originated from East Asian domestic dogs and was introduced through the Southeast Asian archipelago into Australia, with a common ancestry between the Australian dingo and the New Guinea singing dog. In 1758, the taxonomist Linnaeus published in his "Systema Naturae" the taxonomic classification of species. "Canis" is a Latin word meaning dog, and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals.
Dingo
The dingo ("Canis lupus dingo" or "Canis dingo") is a type of feral dog native to Australia. The first British colonists to arrive in 1788 established a settlement at Port Jackson and recorded dingoes living there with indigenous Australians. Although the dingo exists in the wild, it associates with humans but has not been selectively bred similarly to other domesticated animals. It is a medium-sized canid that possesses a lean, hardy body designed for speed, agility and stamina. The dingo's three main coat colours are described as being either light ginger (or tan), black and tan, or creamy white.
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.
Subspecies of Canis lupus
"Canis lupus" has 38 subspecies currently described in the taxonomic authority Mammal Species of the World, including the dingo, "Canis lupus dingo", and the domestic dog, "Canis lupus familiaris", and many subspecies of wolf throughout the Northern Hemisphere. The nominate subspecies is "Canis lupus lupus". "Canis lupus" is assessed as least concern by the IUCN, as its relatively widespread range and stable population trend mean that the species, at global level, does not meet, or nearly meet, any of the criteria for the threatened categories. However, some local populations are classified as endangered, and some subspecies are endangered or extinct.
Canid hybrid
Canid hybrids are the result of interbreeding between different species of the canine (dog) family (genus "Canis"). They often occur in the wild, in particular between domestic or feral dogs and wild native canids. The wolf-like canids are a group of large carnivores that are genetically closely related because their chromosomes number 78. The group includes genus "Canis", "Cuon" and "Lycaon". The members are the dog "(C. lupus familiaris)", gray wolf ("C. lupus"), coyote ("C. latrans"), golden jackal ("C. aureus"), Ethiopian wolf ("C. simensis"), black-backed jackal ("C. mesomelas"), side-striped jackal ("C. adustus"), dhole ("Cuon alpinus"), and African wild dog ("Lycaon pictus").

Not currently. The closest living relative to the dog is the gray wolf? Kinda cool to think about!
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.

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.
Dire wolf
The dire wolf ("Canis dirus", "fearsome dog") is an extinct species of the genus "Canis". It is one of the most famous prehistoric carnivores in North America, along with its extinct competitor, the sabre-toothed cat "Smilodon fatalis". The dire wolf lived in the Americas during the Late Pleistocene epoch (125,000–10,000 years ago). The species was named in 1858, four years after the first specimen had been found. Two subspecies are recognized, these being "Canis dirus guildayi" and "Canis dirus dirus". The dire wolf probably evolved from Armbruster's wolf ("Canis armbrusteri") in North America.

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.
Eastern wolf
The eastern wolf ("Canis lycaon" or "Canis lupus lycaon"), also known as the eastern timber wolf, Algonquin wolf or deer wolf, is a canid native to the northeastern side of North America's Great Lakes region. It is a medium-sized canid which, like the red wolf, is intermediate in size between the coyote and the gray wolf. It primarily preys on white-tailed deer, but may occasionally attack moose and beaver. The eastern wolf's taxonomic classification has been under review beginning c. 2000, with various suggestions having been presented as to its derivation, including its being a subspecies of gray wolf, its being conspecific with the red wolf, gray wolf–coyote hybridization, and classification as a separate species within "Canis".

Yep that's true! There's no evidence that any other canine had contributed to its genetics.

Laurence Yep
Laurence Michael Yep (; born June 14, 1948) is a prolific Chinese-American writer, best known for children's books. In 2005, he received the biennial Laura Ingalls Wilder Medal for his career contribution to American children's literature. Yep was born in San Francisco to Yep Gim Lew (Thomas) and Franche. His older brother, Thomas, named him after studying a particular saint in a multicultural neighborhood that consisted of mostly African Americans. Growing up, he often felt torn between U.S. and Chinese culture, and expressed this in many of his books. A great deal of his work involves characters feeling alienated or not fitting into their surroundings and environment, something Yep has struggled with since childhood.
Elaine Ostrander
Elaine Ann Ostrander is an American geneticist at the National Human Genome Research Institute (NHGRI) of the National Institutes of Health (NIH) in Bethesda, Maryland She holds a number of professional academic appointments, currently serving as Distinguished and Senior Investigator and head of the NHGRI Section of Comparative Genomics; and Chief of the Cancer Genetics and Comparative Genomics Branch. She is known for her research on prostate cancer susceptibility in humans and for conducting genetic investigations with the "Canis familiaris", the domestic dog model, which she has used to study disease susceptibility and frequency and other aspects of natural variation across mammals.
Human evolution
Human evolution is the evolutionary process that led to the emergence of anatomically modern humans, beginning with the evolutionary history of primates – in particular genus "Homo" – and leading to the emergence of "Homo sapiens" as a distinct species of the hominid family, the great apes. This process involved the gradual development of traits such as human bipedalism and language. The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, paleontology, neurobiology, ethology, linguistics, evolutionary psychology, embryology and genetics.
Animal psychopathology
Animal psychopathology is the study of mental or behavioral disorders in animals. Historically, there has been an anthropocentric tendency to emphasize the study of animal psychopathologies as models for human mental illnesses. But animal psychopathologies can, from an evolutionary point of view, be more properly regarded as non-adaptive behaviors due to some sort of a cognitive disability, emotional impairment or distress. This article provides a non-exhaustive list of animal psychopathologies. Animals in the wild appear to be relatively free from eating disorders although their body composition fluctuates depending on seasonal and reproductive cycles.
Dragon (fantasy series)
The Dragon series is a tetralogy of fantasy novels by Chinese American author Laurence Yep. Yep had already written several books including the Newbery Honor novel "Dragonwings" by 1980, when, after undertaking careful research, he decided to adapt Chinese mythology into a fantasy form, something he had always wanted to do since he had sold his first science fiction story at 18. He "tried to stay true to the spirit" of these myths, but did not try "to keep their exact details". The "perfect vehicle" he chose was a folktale in which the Monkey King captured a river spirit who had flooded an entire city, which he at first tried to conceive in picture book form.
Dmitry Belyayev (zoologist)
Dmitry Konstantinovich Belyayev (Russian: Дмитрий Константинович Беляев, 17 July 1917 – 14 November 1985) was a Russian geneticist and academician who served as director of the Institute of Cytology and Genetics (IC&G) of the USSR Academy of Sciences, Novosibirsk, from 1959 to 1985. His decades-long effort to breed domesticated foxes was described by "The New York Times" as “arguably the most extraordinary breeding experiment ever conducted.” A 2010 article in Scientific American stated that Belyayev “may be the man most responsible for our understanding of the process by which wolves were domesticated into our canine companions.”  Beginning in the 1950s, in order to uncover the genetic basis of the distinctive behavioral and physiological attributes of domesticated animals, Belyayev and his team spent decades breeding the wild silver fox ("Vulpes vulpes") and selecting for reproduction only those individuals in each generation that showed the least fear of humans.

Wow fascinating.  You know your canine history.  Wolves are such amazing creatures I never realised they were related to the domestic dog.

Isn't it cool to think about that? Especially given how diverse dogs are, and vary so much! From the pug to the Borzoi to the Great Dane!
Dogs vary widely in shape, size and colors.

Great Dane
The Great Dane is a large German breed of domestic dog known for its giant size. The German name of the breed is "Deutsche Dogge", or German Mastiff. The French name is "Dogue Allemand." The Great Dane is one of the tallest dog breeds. The record holder for tallest dog was a Great Dane called Zeus (died September 2014; aged 5), that measured from paw to shoulder. Large boarhounds resembling the Great Dane appear in ancient Greece, in frescoes from Tiryns dating back to the 14th–13th centuries BC. These large boarhounds continue to appear throughout ancient Greece in subsequent centuries up to the Hellenistic era.
Borzoi
The Borzoi (, literally "fast"), also called the Russian wolfhound (), is a breed of domestic dog ("Canis lupus familiaris"). Descended from dogs brought to Russia from central Asian countries, it is similar in shape to a greyhound, and is also a member of the sighthound family. The system by which Russians over the ages named their sighthounds was a series of descriptive terms, not actual names. "Borzói" is the masculine singular form of an archaic Russian adjective that means "fast". "Borzáya sobáka" ("fast dog") is the basic term used by Russians, though "sobáka" is usually dropped. The name "Psovaya" derived from the word Psovina, which means "wavy, silky coat", just as "Hortaya" (as in Hortaya Borzaya) means shorthaired.
Dog anatomy
Dog anatomy comprises the anatomical studies of the visible parts of the body of a canine. Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, as dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that stood only at the shoulder, in length along the head and body, and weighed only . The largest known adult dog was an English Mastiff which weighed and was from the snout to the tail. The tallest known adult dog is a Great Dane that stands at the shoulder. Source:  The following is a list of the muscles in the dog along with their origin, insertion, action and innervation.
List of Scooby-Doo characters
This is a list of "Scooby-Doo" characters. Scooby-Doo is an American animated franchise based around several animated television series and animated, as well as live action, movies. There are five main characters in the franchise: Scooby-Doo, Shaggy Rogers, Fred Jones, Velma Dinkley, and Daphne Blake—known as "Mystery Incorporated". There are also several recurring characters throughout the franchise, including their parents, friends, allies, and enemies. The original series, "Scooby-Doo, Where Are You? ", premiered in 1969, and has spawned off many follow-up series, and several direct-to-DVD movies.
Guard dog
A guard dog or watch dog (not to be confused with the attack dog) is a dog used to guard against, and watch for unwanted or unexpected people or animals. The dog is discriminating so that it does not annoy or attack familiar people. Both guard dogs and watchdogs bark loudly to alert their owners of an intruder's presence and to scare away the intruder. The watch dog's function ends here; a guard dog is capable of attacking, or restraining the intruder. Livestock guardian dogs are often large enough, 100-200 lbs and strong enough to attack and drive away livestock predators such as wolves. Some smaller breeds (such as Keeshond and Tibetan Terrier) are excellent watchdogs but not guard dogs because they bark loudly to alert their masters of intruders but are physically small and not given to assertive behavior.
Dog fighting
Dog fighting is a type of blood sport generally defined as two or more game dogs against one another in a ring or a pit for the entertainment of the spectators or the gratification of the dogfighters, who are sometimes referred to as dogmen. In rural areas, fights are often staged in barns or outdoor pits; in urban areas, fights may occur in garages, basements, warehouses, abandoned buildings, back alleys, neighborhood playgrounds, or in the streets. Dog fights usually last until one dog is declared a winner, which occurs when one dog fails to scratch, one dog dies, or one dog jumps out of the pit.
Scooby-Doo (character)
Scoobert "Scooby" Doo is the eponymous character and protagonist of the animated television franchise of the same name created in 1969 by the American animation company Hanna-Barbera. Scooby-Doo is a male Great Dane and lifelong companion of amateur detective Shaggy Rogers, with whom he shares many personality traits. Named after a nonsense vocal line in Frank Sinatra's hit song "Strangers in the Night", he features a mix of both canine and human behaviors (reminiscent of other funny animals in the Golden age of American animation), treated by his friends more or less as an equal while speaking in a famous (and much parodied) speech impediment.
