According to statistics published by the American Pet Products Manufacturers Association in the National Pet Owner Survey in 2009–2010, an estimated 77.5 million people in the United States have pet dogs. In the 1980s, there have been changes in the pet dog's functions, such as the increased role of dogs in the emotional support of their human guardians. Compared to wolves, dogs from agricultural societies have extra copies of amylase and other genes involved in starch digestion that contribute to an increased ability to thrive on a starch-rich diet.

Their pathology is similar to that of humans, as is their response to treatment and their outcomes. Dogs can have a violet gland (or supracaudal gland) characterized by sebaceous glands on the dorsal surface of their tails; in some breeds, it may be vestigial or absent. The coats of certain breeds are often groomed to a characteristic style, for example, the Yorkshire Terrier's "show cut". They can pick up the slightest sounds from about 400 m (1,300 ft) compared to 90 m (300 ft) for humans. While the human brain is dominated by a large visual cortex, the dog brain is dominated by a large olfactory cortex. They have difficulty differentiating between red and green, and much like other mammals, the dog's eye is composed of two types of cone cells compared to the human's three.

Dog crossbreeds are combinations of lineages of the domestic dog; they are distinguished from canid hybrids, which are interspecific crosses between Canis species (wolves, coyotes, jackals, etc.). Recognized dog breeds are classified by groups, such as Hound, Terrier, Working, Herding, Sporting, Non-Sporting, Toy and Miscellaneous; some groups may be further subdivided by some registries. They often serve as registries, which are lists of adult purebred dogs and lists of litters of puppies born to purebred parents. Groups of owners that have dogs of the same breed and have an interest in dog breeding can form national Kennel clubs. The study indicated that throughout history, global dog populations experienced numerous episodes of diversification and homogenization, with each round further reducing the power of genetic data derived from modern breeds to help infer their early history.
- Feral and free-ranging dogs’ potential to compete with other large carnivores is limited by their strong association with humans.
- A dog breed will consistently produce the physical traits, movement and temperament that were developed over decades of selective breeding.

In Hindu mythology, Yama, the god of death, owns two watchdogs named Shyama and Sharvara, which each have four eyes—they are said to watch over the gates of Naraka. Stories of dogs guarding the gates of dog the underworld recur throughout Indo-European mythologies and may originate from Proto-Indo-European traditions. In the Neo-Assyrian and Neo-Babylonian periods, dogs served as emblems of magical protection. Artworks have depicted dogs as symbols of guidance, protection, loyalty, fidelity, faithfulness, alertness, and love. In one study, new guardians reported a significant reduction in minor health problems during the first month following pet acquisition, which was sustained through the 10-month study. In a 2015 study, it was found that having a pet made people more inclined to foster positive relationships with their neighbors.
