Unlike other domestic species which were primarily selected for production-related traits, dogs were initially selected for their behaviors.[96][97] In 2016, a study found that there were only 11 fixed genes that showed variation between wolves and dogs. These gene variations were unlikely to have been the result of natural evolution, and indicate selection on both morphology and behavior during dog domestication. These genes have been shown to affect the catecholamine synthesis pathway, with the majority of the genes affecting the fight-or-flight response[97][98] (i.e. selection for tameness), and emotional processing.[97] Dogs generally show reduced fear and aggression compared with wolves.[97][99] Some of these genes have been associated with aggression in some dog breeds, indicating their importance in both the initial domestication and then later in breed formation.[97] Traits of high sociability and lack of fear in dogs may include genetic modifications related to Williams-Beuren syndrome in humans, which cause hypersociability at the expense of problem solving ability.[100][101][102]

Domestic dogs inherited complex behaviors, such as bite inhibition, from their wolf ancestors, which would have been pack hunters with complex body language. These sophisticated forms of social cognition and communication may account for their trainability, playfulness, and ability to fit into human households and social situations, and these attributes have given dogs a relationship with humans that has enabled them to become one of the most successful species on the planet today.[132]:pages95-136
Neutering reduces problems caused by hypersexuality, especially in male dogs.[76] Spayed female dogs are less likely to develop some forms of cancer, affecting mammary glands, ovaries, and other reproductive organs.[77] However, neutering increases the risk of urinary incontinence in female dogs,[78] and prostate cancer in males,[79] as well as osteosarcoma, hemangiosarcoma, cruciate ligament rupture, obesity, and diabetes mellitus in either sex.[80]
Various kinds of service dogs and assistance dogs, including guide dogs, hearing dogs, mobility assistance dogs, and psychiatric service dogs provide assistance to individuals with disabilities.[160][161] Some dogs owned by epileptics have been shown to alert their handler when the handler shows signs of an impending seizure, sometimes well in advance of onset, allowing the guardian to seek safety, medication, or medical care.[162]
Toxocara canis (dog roundworm) eggs in dog feces can cause toxocariasis. In the United States, about 10,000 cases of Toxocara infection are reported in humans each year, and almost 14% of the U.S. population is infected.[185] In Great Britain, 24% of soil samples taken from public parks contained T. canis eggs.[186][failed verification] Untreated toxocariasis can cause retinal damage and decreased vision.[186] Dog feces can also contain hookworms that cause cutaneous larva migrans in humans.[187][188][189][190]

Wolves kill dogs wherever they are found together.[111] One study reported that in Wisconsin in 1999 more compensation had been paid for losses due to wolves taking dogs than for wolves taking livestock. In Wisconsin wolves will often kill hunting dogs, possibly because the dogs are in the wolf's territory.[111] A strategy has been reported in Russia where one wolf lures a dog into heavy brush where another wolf waits in ambush.[112] In some instances, wolves have displayed an uncharacteristic fearlessness of humans and buildings when attacking dogs, to the extent that they have to be beaten off or killed.[113] Although the numbers of dogs killed each year are relatively low, it induces a fear of wolves entering villages and farmyards to take dogs, and losses of dogs to wolves has led to demands for more liberal wolf hunting regulations.[108]
Dog intelligence is the ability of the dog to perceive information and retain it as knowledge for applying to solve problems. Dogs have been shown to learn by inference. A study with Rico showed that he knew the labels of over 200 different items. He inferred the names of novel items by exclusion learning and correctly retrieved those novel items immediately and also 4 weeks after the initial exposure. Dogs have advanced memory skills. A study documented the learning and memory capabilities of a border collie, "Chaser", who had learned the names and could associate by verbal command over 1,000 words[87]. Dogs are able to read and react appropriately to human body language such as gesturing and pointing, and to understand human voice commands, although a 2018 study on canine cognitive abilities found that dogs' capabilities are not more exceptional than those of other animals, such as horses, chimpanzees or cats.[88]
"The most widespread form of interspecies bonding occurs between humans and dogs"[136] and the keeping of dogs as companions, particularly by elites, has a long history.[142] (As a possible example, at the Natufian culture site of Ain Mallaha in Israel, dated to 12,000 BC, the remains of an elderly human and a four-to-five-month-old puppy were found buried together).[22] However, pet dog populations grew significantly after World War II as suburbanization increased.[142] In the 1950s and 1960s, dogs were kept outside more often than they tend to be today[143] (using the expression "in the doghouse" to describe exclusion from the group signifies the distance between the doghouse and the home) and were still primarily functional, acting as a guard, children's playmate, or walking companion. From the 1980s, there have been changes in the role of the pet dog, such as the increased role of dogs in the emotional support of their human guardians.[144] People and dogs have become increasingly integrated and implicated in each other's lives,[145] to the point where pet dogs actively shape the way a family and home are experienced.[146]
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.

Certain Pacific islands whose maritime settlers did not bring dogs, or where dogs died out after original settlement, notably: the Mariana Islands,[123] Palau,[124] Marshall Islands,[125] Gilbert Islands,[125] New Caledonia,[126] Vanuatu,[126][127] Tonga,[127] Marquesas,[127] Mangaia in the Cook Islands, Rapa Iti in French Polynesia, Easter Island,[127] Chatham Islands,[128] and Pitcairn Island (settled by the Bounty mutineers, who killed off their dogs in order to escape discovery by passing ships[129]).
You may need to pluck ear hairs from time to time. Ask a veterinarian or professional groomer to show you how to pluck the hairs from your dog's ear safely and correctly. Ear powder makes the process easier and quicker by giving added gripping power to the slippery ear hairs. Be very careful when using hemostats as they may poke inside their ear if used incorrectly or when the dog jerks their head.
In mythology, dogs often serve as pets or as watchdogs.[208] Stories of dogs guarding the gates of the underworld recur throughout Indo-European mythologies[210][211] and may originate from Proto-Indo-European religion.[210][211] In Greek mythology, Cerberus is a three-headed watchdog who guards the gates of Hades.[208] In Norse mythology, a bloody, four-eyed dog called Garmr guards Helheim.[208] In Persian mythology, two four-eyed dogs guard the Chinvat Bridge.[208] In Welsh mythology, Annwn is guarded by Cŵn Annwn.[208] In Hindu mythology, Yama, the god of death, owns two watch dogs who have four eyes. They are said to watch over the gates of Naraka.[212]

The role of the dog in Chinese mythology includes a position as one of the twelve animals which cyclically represent years (the zodiacal dog). Three of the 88 constellations in western astronomy also represent dogs: Canis Major (the Great Dog, whose brightest star, Sirius, is also called the Dog Star), Canis Minor (the Little Dog), and Canes Venatici (the Hunting Dogs).
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 communication is how dogs convey information to other dogs, how they understand messages from humans, and how humans translate the information that dogs are transmitting.[103]:xii Communication behaviors of dogs include eye gaze, facial expression, vocalization, body posture (including movements of bodies and limbs) and gustatory communication (scents, pheromones and taste). Humans communicate to dogs by using vocalization, hand signals and body posture.
Dog grooming is so much more than giving your dog a bath. Dog grooming is a broad term that covers all aspects of canine cleanliness and hygiene. The services included in dog grooming will vary based on your needs and what you choose to pay. Unless they are rolling in cowpies or playing in mud puddles, most dogs are okay getting a shampoo bath only as needed. You’ll know when they need it if they smell bad or are bringing dirt into the house. Some dogs, like shepherds and shih tzus, have thick coats that can get matted and tangled without regular care. Pro dog groomers can deftly blow dry a dog’s hair after a bath so that it is shiny and smooth. Dog grooming can include brushing that detangles dog hair and also thins the undercoat to minimize shedding.

Despite their close genetic relationship and the ability to inter-breed, there are a number of diagnostic features to distinguish the gray wolves from domestic dogs. Domesticated dogs are clearly distinguishable from wolves by starch gel electrophoresis of red blood cell acid phosphatase.[41] The tympanic bullae are large, convex and almost spherical in gray wolves, while the bullae of dogs are smaller, compressed and slightly crumpled.[42] Compared with equally sized wolves, dogs tend to have 20% smaller skulls and 30% smaller brains.[43]:35 The teeth of gray wolves are also proportionately larger than those of dogs.[44] Dogs have a more domed forehead and a distinctive "stop" between forehead and nose.[45] The temporalis muscle that closes the jaws is more robust in wolves.[5]:p158 Wolves do not have dewclaws on their back legs, unless there has been admixture with dogs that had them.[46] Most dogs lack a functioning pre-caudal gland and enter estrus twice yearly, unlike gray wolves which only do so once a year.[47] So-called primitive dogs such as dingoes and Basenjis retain the yearly estrus cycle.[48]
