The term “domestic dog” refers to any of several hundred breeds of dog in the world today. While these animals vary drastically in appearance, every dog—from the Chihuahua to the Great Dane is a member of the same species, Canis familiaris. This separates domestic dogs from wild canines, such as coyotes, foxes, and wolves.
COMMON NAME: Domestic dogs
SCIENTIFIC NAME: Canis familiaris
SIZE: Five to 35 inches at the shoulder
WEIGHT: Three to 250 pounds
SIZE RELATIVE TO A 6-FT MAN
Today, many of the dogs you know and love are the product of selective breeding between individuals with desirable traits, either physical or behavioral. For instance, around 9,500 years ago, ancient peoples began breeding dogs that were best able to survive and work in the cold. These dogs would become the family of sled dogs—including breeds such as huskies and malamutes—that remains relatively unchanged today.
Similarly, humans bred German shepherds for their ability to herd livestock, Labrador retrievers to help collect ducks and other game felled by hunters, and sausage-shaped Dachshunds for their ability to rush down a burrow after a badger. Many more breeds were created to fill other human needs, such as home protection and vermin control.
Certain breeds have also been created to make dogs more desirable as companions. For instance, the labradoodle, which combines the traits of a Labrador retriever and a poodle, was invented as an attempt to create a hypoallergenic guide dog.
It is becoming popular to breed together two different breeds of dogs and call the new dog’s breed a name that is a mixture of the parents’ breeds’ two names. A puppy with a poodle and a Pomeranian as parents might be called a Pomapoo. These kinds of dogs, instead of being called mutts, are known as designer dog breeds.
Living with dogs
Most dogs are a mix of breeds—in 2015, one study estimated that only 5 percent of dogs in shelters are purebred. Just as dogs come in all sizes, shapes, and colors, these animals also come in a spectrum of temperaments. A bulldog might look fierce but be cuddly as a kitten, whereas a cute cocker spaniel might nip at your finger without thinking twice.
This is why animal handling expert Jack Hanna recommends teaching children to always exercise caution around a dog they do not know. For instance, he says kids should ask for permission from the dog’s owner before trying to pet or play with the animal. Offering an outstretched hand also allows the dog to familiarize itself with a new person before reaching behind its head where it can’t see what you’re doing, which might make a dog nervous or scared. Finally, never allow children to put their faces near the dog’s muzzle.
Dogs and humans
Dogs are often called “man’s best friend” because they fit in with human life. Man refers to humankind and not just guys (Old English). Dogs can serve people in many ways. For example, there are guard dogs, hunting dogs, herding dogs, guide dogs for blind people, and police dogs. There are also dogs that are trained to smell for diseases in the human body or to find bombs or illegal drugs. These dogs sometimes help police in airports or other areas.
Sniffer dogs (usually beagles) are sometimes trained for this job. Dogs have even been sent by Russians into outer space, a few years before any human being. The first dog sent up was named Laika, but she died within a few hours.
