Dogs are the first domesticated animal and commonly known as "man's best friend". Dogs accompany humans and have been considered pets for approximately 10,000 years. used for working, hunting, but most commonly as a pet. Today there are hundreds of different dog breeds, of various sizes, colors and shapes. Although dogs are currently seen primarily as pets, they have not always been viewed as such and have had their own evolution. To fully understand dogs, you need to take a look at their origin and how they evolved. Dogs are a subspecies of the gray wolf and have inherited many behaviors from their wolf ancestors they have evolved, which make up much of what wolves are, however they remain wilder than dogs with tendencies such as the "ungulate"-based diet or large hooved mammals, such as moose, deer, moose, and caribou. Wolves are also known to eat beavers, rabbits, and other small prey" (basic). Wolves, unlike dogs, prey on other animals to survive, while domesticated dogs typically eat dog food. Dog food typically is available in three varieties, including raw food, wet food, and dry food, most of which are store-brand and store-bought. Many forms of dog food are meat-based, similar to the gray wolf's carnivorous diet. in addition to store-bought commercial food, domesticated dogs, however, form natural instincts that tend to make them sometimes chase smaller prey. Communication patterns have also been passed down from gray wolves to dogs, as the behaviors dogs have inherited from Wolves include "a complex communication system ranging from barking to barking. to growl and howl" (Basic). Dogs commonly display barking to display a variety of emotions and bark in...... middle of paper ...... of wolves, and evolved specifically from the species of gray wolf. This evolution began about 10,000 years ago when the first dogs were domesticated. Although it is still disputed how exactly dogs were domesticated, it has been accepted that human interaction most likely has something to do with it still the possibility that dogs domesticated themselves rather than humans, having a greater impact on the domestication of dogs. The exact circumstances of how this officially occurred may never be known to become the animals and pets that humans know and love today. They are used for many jobs in the business world and are one of the most popular pets for people around the world. Hundreds of different dog breeds have been bred, and dogs continue to be one of the most genetically diverse animals on Earth.
