The origin of the domestic dog includes the dog's evolutionary divergence from the wolf, its domestication, and its development into dog types and dog breeds. The dog is a member of the genus Canis, which forms part of the wolf-like canids, and was the first species and the only large carnivore to have been domesticated.[14][26] The dog and the extant gray wolf are sister taxa, as modern wolves are not closely related to the population of wolves that was first domesticated.[14]

Dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier, that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head-and-body, and weighed only 113 grams (4.0 oz). The largest known dog was an English Mastiff which weighed 155.6 kg (343 lb) and was 250 cm (98 in) from the snout to the tail.[31] The tallest dog is a Great Dane that stands 106.7 cm (42.0 in) at the shoulder.[32]

In 2013, an estimate of the global dog population was 987 million.[104] Although it is said that the "dog is man's best friend",[105] this refers largely to the ~20% of dogs that live in developed countries. In the developing world, dogs are more commonly feral or communally owned, with pet dogs uncommon.[50] Most of these dogs live their lives as scavengers and have never been owned by humans, with one study showing their most common response when approached by strangers is to run away (52%) or respond aggressively (11%).[106] Little is known about these dogs, or the dogs in developed countries that are feral, stray or are in shelters, because the great majority of modern research on dog cognition has focused on pet dogs living in human homes.[107]


The practice of using dogs and other animals as a part of therapy dates back to the late 18th century, when animals were introduced into mental institutions to help socialize patients with mental disorders.[201] Animal-assisted intervention research has shown that animal-assisted therapy with a dog can increase social behaviors, such as smiling and laughing, among people with Alzheimer's disease.[202] One study demonstrated that children with ADHD and conduct disorders who participated in an education program with dogs and other animals showed increased attendance, increased knowledge and skill objectives, and decreased antisocial and violent behavior compared with those who were not in an animal-assisted program.[203]


Dry your dog. Use a squeegee or use your hand as a squeegee to force water off of the coat and body. Towel dry him as best as you can while he's still in the tub, so you don't make a mess. Place the towel over your dog’s back, or hold it next to him and give permission to shake the water off their body. Many dogs will learn the “bath rules” and wait to shake until you have placed the towel over them to contain the water droplets. Another type of towel to use is a chamois, which is a thin fleece like towel that is designed to be wrung out when wet. It lessens the amount of towels needed and does the bulk of the work. Using a chamois, then a towel makes drying less of a hassle.

According to the Humane Society of the United States, 3–4 million dogs and cats are euthanized each year in the United States and many more are confined to cages in shelters because there are many more animals than there are homes. Spaying or castrating dogs helps keep overpopulation down.[75] Local humane societies, SPCAs, and other animal protection organizations urge people to neuter their pets and to adopt animals from shelters instead of purchasing them.
In 1999, a study of mitochondrial DNA indicated that the domestic dog may have originated from multiple grey wolf populations, with the dingo and New Guinea singing dog "breeds" having developed at a time when human populations were more isolated from each other.[23] In the third edition of Mammal Species of the World published in 2005, the mammalogist W. Christopher Wozencraft listed under the wolf Canis lupus its wild subspecies, and proposed two additional subspecies: "familiaris Linneaus, 1758 [domestic dog]" and "dingo Meyer, 1793 [domestic dog]". Wozencraft included hallstromi – the New Guinea singing dog – as a taxonomic synonym for the dingo. Wozencraft referred to the mDNA study as one of the guides in forming his decision.[1] The inclusion of familiaris and dingo under a "domestic dog" clade has been noted by other mammalogists.[24] This classification by Wozencraft is debated among zoologists.[25]

Dogs have been described as carnivores[117][118] or omnivores.[17][119][120][121] Compared to wolves, dogs have genes involved in starch digestion that contribute to an increased ability to thrive on a starch-rich diet.[19] Based on metabolism and nutrition, many consider the dog to be an omnivore. However, the dog is not simply an omnivore. More like the cat and less like other omnivores, the dog can only produce bile acid with taurine, and it cannot produce vitamin D, which it obtains from animal flesh. Also more like the cat, the dog requires arginine to maintain its nitrogen balance. These nutritional requirements place the dog part-way between carnivores and omnivores.[122]

In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his Systema Naturae the binomial nomenclature – or the two-word naming – of species. Canis is the Latin word meaning "dog",[21] and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals. He classified the domestic dog as Canis familiaris, and on the next page he classified the wolf as Canis lupus.[3] Linnaeus considered the dog to be a separate species from the wolf because of its cauda recurvata - its upturning tail which is not found in any other canid.[22]

Human emigrants from Siberia that came across the Bering land bridge into North America likely had dogs in their company. Although one writer[139] even suggests that the use of sled dogs may have been critical to the success of the waves that entered North America roughly 12,000 years ago,[139] the earliest archaeological evidence of dog-like canids in North America dates from about 9,400 years ago.[132]:104[140] Dogs were an important part of life for the Athabascan population in North America, and were their only domesticated animal. Dogs as pack animals may have contributed migration of the Apache and Navajo tribes 1,400 years ago. This use of dogs in these cultures often persisted after the introduction of the horse to North America.[141]
Dog meat is consumed in some East Asian countries, including Korea, China[133] and Vietnam,[134] a practice that dates back to antiquity.[164] It is estimated that 13–16 million dogs are killed and consumed in Asia every year.[165] In China, debates have ensued over banning the consumption of dog meat.[166] Following the Sui and Tang dynasties of the first millennium, however, people living on the plains of northern China began to eschew eating dogs. This is likely due to the spread of Buddhism and Islam, two religions that forbade the consumption of certain animals, including dogs. As members of the upper classes shunned dog meat, it gradually became a social taboo to eat it, despite the fact that the general population continued to consume it for centuries afterward.[167] Other cultures, such as Polynesia and pre-Columbian Mexico, also consumed dog meat in their history. However, Western, South Asian, African, and Middle Eastern cultures, in general, regard consumption of dog meat as taboo. In some places, however, such as in rural areas of Poland, dog fat is believed to have medicinal properties – being good for the lungs for instance.[168] Dog meat is also consumed in some parts of Switzerland.[169] Proponents of eating dog meat have argued that placing a distinction between livestock and dogs is western hypocrisy, and that there is no difference with eating the meat of different animals.[170][171][172][173]
A number of common human foods and household ingestibles are toxic to dogs, including chocolate solids (theobromine poisoning), onion and garlic (thiosulphate, sulfoxide or disulfide poisoning),[54] grapes and raisins, macadamia nuts, xylitol,[55] as well as various plants and other potentially ingested materials.[56][57] The nicotine in tobacco can also be dangerous. Dogs can be exposed to the substance by scavenging through garbage bins or ashtrays and eating cigars and cigarettes. Signs can be vomiting of large amounts (e.g., from eating cigar butts) or diarrhea. Some other signs are abdominal pain, loss of coordination, collapse, or death.[58] Dogs are susceptible to theobromine poisoning, typically from ingestion of chocolate. Theobromine is toxic to dogs because, although the dog's metabolism is capable of breaking down the chemical, the process is so slow that for some dogs even small amounts of chocolate can be fatal, especially dark chocolate.
Be patient. You may have to go over your dog's coat a few times before you have a smooth, even cut. Don't rush it! Give your dog as many breaks as necessary, and make sure to move your clippers slowly. Brushing up against the coat then going the spot with clippers again help to get a smooth cut. Do will have to be done many times before you are done.

Dog behavior is the internally coordinated responses (actions or inactions) of the domestic dog (individuals or groups) to internal and/or external stimuli.[94] As the oldest domesticated species, with estimates ranging from 9,000–30,000 years BCE, the minds of dogs inevitably have been shaped by millennia of contact with humans. 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 human behaviors.[18] Behavioral scientists have uncovered a surprising set of social-cognitive abilities in the domestic dog. These abilities are not possessed by the dog's closest canine relatives nor by other highly intelligent mammals such as great apes but rather parallel some of the social-cognitive skills of human children.[95]
"While new to thumbtack, we have over 20 years of experience, a 5 star rating online & we're reasonably priced! Background: Our founder grew up around street dogs, aggressive dogs, and so-called dangerous breeds. And has been around dogs for more than 20 years and understands them (and other animals) better than he understands people. His core values, which are apart of the company are: Value, Respect, Compassion, Integrity & Love We can help you train your pup, exercise them, housebreak them and teach you basic tactics to overcome their basic behavioral issues. We have experience with rottweilers, German shepherds, pit-bulls and other large breeds. I believe there are no bad dogs, just bad manners trained into them by accident. We love playing with them, roughhousing with them and teaching them things. Here is a free pro-tip; dogs love being scratched where they can't reach. The favorite location is the back of their hind legs, base of the spine on their back (in between the shoulder blades), & the base of the tail... BUT, you have to scratch very, very hard. Be forewarned, they will forever greet you with their rear facing you. :)"
