My favorite pet is a dog. A dog is a friend of people. With a dog is always fun and interesting. The dog is the most true four-pawed animal. A dog is one of the most common pets. The dog is the very first animal that a man could tame. There are several assumptions about where these animals originated. Some scientists consider the ancestors of the domestic dog to be wolves and jackals, others think that the only ancestor of the dog is a wolf.
How did people manage to domesticate a wolf? There are two hypotheses. First, people themselves took the initiative to tame a wild animal. The second version - in search of food, protection and new territory, wild wolves themselves came to people.
Dogs were the first animals to become companions and faithful helpers of people. As soon as primitive people discovered agriculture, they immediately started breeding dogs for various useful purposes. Dogs guarded dwellings and domestic cattle, helped hunters and shepherds. On cold nights a devoted four-legged friend warmed the owner with his body. Ancient excavations indicate that the dogs were buried with their owners.
Since ancient times, there have been many different breeds of dogs. To date, there are 337 canine breeds in the world.
I like dogs.
