|Nine different breeds of dogs.|
C. l. familiaris
Dogs (Canis lupus familiaris) are domesticated mammals, not natural wild animals. They were originally bred from wolves. They have been bred by humans for a long time, and probably were the first animals to be domesticated.
Today, some dogs are used as pets while others are used to help humans do their work. Dogs are popular pets because they are usually playful, friendly, and listen well to humans. Thirty million dogs in the United States are registered as pets. Dogs eat both meat and vegetables, often mixed together and sold in stores as dog food. Dogs often have jobs, including police dogs, army dogs, service dogs, fire dogs, messenger dogs, hunting dogs, herding dogs, or rescue dogs.
Dogs are sometimes called "canines," which comes from the Latin word for dog - canis. Sometimes people also use "dog" to describe other canids, such as wolves. A baby dog is called a pup or puppy. A dog is called a puppy until it is about one year old.
Dogs are sometimes referred to as "man's best friend" because they are kept as domestic pets and are usually loyal and like being around humans.
Appearance and Behavior
Dogs can smell and hear better than humans, but cannot see well in color. Due to the structure of the eye, dogs can see better in dim light than humans. They can also see further around before moving their eyes than a human can.
Like wolves, wild dogs travel in groups called packs. Packs of dogs are ordered by rank, and dogs with low rank will submit to other dogs with a higher rank. The highest-ranked dog is called the alpha male. Each dog in a pack helps and cares for others. Domesticated dogs often view their owner as the alpha male.
Different dog breeds (kinds) have different lifespans. In general, smaller dogs live longer than larger dogs. The size and the breed of the dog change the average lifespan of a dog. Breeds such as the Dachshund usually live for fifteen years, while Chihuahuas can reach age twenty. The Great Dane, on the other hand, has an average lifespan of six to eight years; some Great Danes have lived for ten years.
Origin of Dogs
The earliest known fossil of a domestic dog is said to be from 31,700 years ago in Belgium. Scientists believe that dogs have lived with people for at least 30,000 years. In 2013, a study was published that showed that the skull and teeth of a canid, dated to 33,000 years ago, had characteristics closer to a dog than to a wolf, and the authors determined that "this specimen may represent a dog in the very early stages of domestication."
Other signs of domestication are that sometimes, dogs were buried together with humans. Evidence of this is a tomb in Bonn, where a man of about 50 years of age, a woman of about 25 years of age, the remains of a dog, and other artifacts were found. Radiocarbon dating showed that the human bones were between 13,300 and 14,000 years old.
Dogs and Humans
Dogs are often called "man's best friend" because they fit well with human life. Dogs can serve people in many ways. For example, there are guard dogs, hunting dogs, herding dogs, guide dogs for blind people (along with other service dogs), and police dogs. 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 was sent. The first dog sent up was named Laika, but she died within a few hours.
It is estimated that three-quarters of the world's dog population lives in the developing world as feral, village, or community dogs. Pet dogs are uncommon in these areas.
Pet dog populations grew after World War II. In the 1950s and 1960s, dogs were kept outside more often than they tend to be today and were still used as guard dogs, children's playmates, or walking companions.
The majority of modern dog owners describe their pet as part of the family. It is estimated there are 77.5 million people with pet dogs in the United States.
The latest study using magnetic resonance imaging (MRI) comparing humans and dogs showed that dogs have the same response to voices and use the same parts of the brain as humans do. This gives dogs the ability to recognize emotional human sounds, making them friendly social pets to humans.
Best Dogs for Kids
The best dogs for kids are ones that have calm personalities and are happy to socialize with everyone in the family.
Having a family dog can also teach children cooperation and responsibility. For example, a child can help with chores such as walking, feeding, and brushing the dog.
Here are some of the most popular dog breeds for kids:
- Cavalier King Charles Spaniel
- Labrador Retriever
- Golden Retriever
- See also List of dog breeds.
There are at least 800 breeds (kinds) of dogs. Dogs whose parents were the same breed will also be that breed: these dogs are called purebred or pure pedigree dogs. Dogs with parents from different breeds no longer belong to one breed: they are called mutts, mixed-breed dogs, hybrids, or mongrels. Some of the most popular breeds are sheepdogs, collies, poodles, and retrievers. It is becoming popular to breed two different breeds of dogs together 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. These dogs are normally used for prize shows and designer shows. They can also be guide dogs.
