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 Christianity, dogs represent faithfulness.[208] Within the Roman Catholic denomination specifically, the iconography of Saint Dominic includes a dog, after the hallow's mother dreamt of a dog springing from her womb and becoming pregnant shortly thereafter.[214] As such, the Dominican Order (Ecclesiastical Latin: Dominicanus) means "dogs of the Lord" or "hounds of the Lord" (Ecclesiastical Latin: domini canis).[214] In Christian folklore, a church grim often takes the form of a black dog to guard Christian churches and their churchyards from sacrilege.[215]
Cultural depictions of dogs in art extend back thousands of years to when dogs were portrayed on the walls of caves. Representations of dogs became more elaborate as individual breeds evolved and the relationships between human and canine developed. Hunting scenes were popular in the Middle Ages and the Renaissance. Dogs were depicted to symbolize guidance, protection, loyalty, fidelity, faithfulness, watchfulness, and love.[219]
The genetic divergence between dogs and wolves occurred between 40,000–20,000 years ago, just before or during the Last Glacial Maximum.[27][2] This timespan represents the upper time-limit for the commencement of domestication because it is the time of divergence and not the time of domestication, which occurred later.[27][28] The domestication of animals commenced over 15,000 years ago, beginning with the grey wolf (Canis lupus) by nomadic hunter-gatherers.[27] The archaeological record and genetic analysis show the remains of the Bonn–Oberkassel dog buried beside humans 14,200 years ago to be the first undisputed dog, with disputed remains occurring 36,000 years ago.[2] It was not until 11,000 years ago that people living in the Near East entered into relationships with wild populations of aurochs, boar, sheep, and goats.[27]

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]
A dog groomer is a service professional who provides dog grooming and basic hygiene care for your dog. Dog groomers are typically animal lovers who are competent and comfortable working with a wide range of dog breeds and temperaments. Dog groomers are knowledgeable about the care needs for different kinds of dog coats. A poodle will have different haircut needs than a shih tzu, for example, so it pays to have a trained pro provide the proper cut. Good dog groomers know how to safely clean your dog’s teeth, bathe your dog, and cut their nails without going too short. They understand how to trim the hair from around your dog’s face, express anal glands, and clean your dog’s ears. Many people who choose dog grooming as a profession also pursue other dog services such as attending veterinary school, running a doggy day care center, working as a professional dog walker, and more.

Dogs generally have brown eyes and wolves almost always have amber or light colored eyes.[49] The skin of domestic dogs tends to be thicker than that of wolves, with some Inuit tribes favoring the former for use as clothing due to its greater resistance to wear and tear in harsh weather.[50] The paws of a dog are half the size of those of a wolf, and their tails tend to curl upwards, another trait not found in wolves.[51] The dog has developed into hundreds of varied breeds, and shows more behavioral and morphological variation than any other land mammal.[52]

Dogs have lived and worked with humans in many roles. In addition to dogs' role as companion animals, dogs have been bred for herding livestock (collies, sheepdogs),[154][17] hunting (hounds, pointers),[43] and rodent control (terriers).[17] Other types of working dogs include search and rescue dogs,[155] detection dogs trained to detect illicit drugs[156] or chemical weapons;[157] guard dogs; dogs who assist fishermen with the use of nets; and dogs that pull loads.[17] In 1957, the dog Laika became the first animal to be launched into Earth orbit, aboard the Soviets' Sputnik 2; she died during the flight.[158][159]

As humans became more sophisticated, so did their dogs. Eventually, there emerged specific breeds of dogs, custom-bred to suit the breeders’ local needs and circumstances. The Greyhound, for instance, was the foundation type for the immense Irish Wolfhound and the dainty Italian Greyhound. All three have a distinct family resemblance, but you’d never mistake one for another.
Clip the dog's nails.[3] If left untrimmed, a dog's nails can curl under into the paw pads or twist toes in a way that causes joint damage. To keep your dog's nails short, clip them regularly, depending on how fast his nails grow. If you can hear his nails on the ground when he walks, that means his nails are touching the ground, and are too long. [4]

Cut out mats that can't be brushed out. Severe matting can pull the skin every time the dog moves, making daily life painful for your pet. If you can't brush a mat out, you need to either cut or shave it off, depending on how close it is to the skin. Be extremely careful if you use scissors to avoid injuring yourself or your pet. Try to cut parallel to the growth of the hair to avoid a choppy look.
