Dogs are one of the earliest domesticated domestic animals of human beings, belonging to the mammalian carnivorous canines, the earliest is produced by the natural hybridization of wolves, foxes and jackals, after different ethnic groups use different methods for a long period of domestication and gradually formed a wide variety of breeds, from ancient times to the present has always been a friend of human friends and powerful assistants, let's take a look at the life habits of dogs!
Food characteristics
Dogs are taxonomically carnivorous. The ancestors of dogs preyed mainly on small animals and occasionally fed them with tubers. After dogs were trained by humans, their feeding habits changed and they became meat-eating omnivores, but vegetarian diets can also sustain life. Even so, they still maintain a meat-based digestive characteristics, such as dog teeth, each with a pair of sharp canine teeth above and below, reflecting the characteristics of carnivores good at biting prey, the dog molars are also sharp and strong, can cut off food, when biting bones, the pressure between the upper and lower teeth can reach 165 kg, but not good at chewing. Therefore, dogs are really "wolfing" when they eat and rarely chew.
Hierarchical concept
Dogs are naturally gregarious, and in dog farms, rural or suburban dog populations, there is always a head dog leading the group and will dominate and govern them. The head dog's chief status is usually expressed by the following specific actions, such as allowing oneself but not allowing the other party to examine the genitals of other dogs, not allowing the other dog to urinate in the direction of the other dog where the urine has been urinated, and the other party can shake his head, swing his tail, be naughty, sit down or lie down in front of the head dog, and stand when the head dog leaves. Once the level advantage is clear, the hostility disappears and you begin to become friends. Therefore, the owner should erect the image of the head dog, not too pampered, and make the dog think that it is the head dog.
Domain concept
Dogs have a strong sense of territory and are accustomed to marking its "sphere of influence" with peeing. In its field, it can be very angry, and once it reaches a strange place, especially a place with a strong smell of dogs and cats, it has no courage. This is often the case when it approaches the animal hospital, refusing to move forward, or trembling, or even drooling nervously. So it often centers on itself, marks the boundaries with its own scent, and is often renewed, and a territory can only belong to one or two dogs or the entire group of dogs.
Barking instinct
Whenever ambulances and police cars pass, dogs often bark. Barking is a common way wolves contact their companions, and as an instinct, dogs inherit this trait. So it's not surprising when you hear about whose dog "sings" to the music. But not all dogs bark, with some exceptions.
Loves to socialize
Interacting with people is a natural habit of dogs, especially with children, and this natural habit often depends on the degree of contact with people at 3 to 7 weeks of age. If a dog is only with its parents or other dogs in the first two months of life, or does not really understand people, it is easy to have a situation of not loving to interact with people and not training well. If it is caressed by people from an early age, this makes it realize that people are its friends and familiar with people's smells. This will develop a character that loves to interact with people and is easy to train.
Homecoming skills
As the saying goes, "the cat finds eight hundred miles, the dog finds a thousand miles." It means that cats and dogs have amazing homecoming skills, and can return to their owners' homes from hundreds of miles away. There are many stories about dogs seeking the Lord. It has been reported that there was a couple in the United States who took their Scottish Shepherd dogs from Silbatten in the western United States to the east, and when they reached Ourut, Indiana, the dogs were lost and looked for nothing. But after about half a year, after a 3300-kilometer trek, the dog's mixed body scars appeared in front of its owner. The physiological basis of the dog's ability to return home varies. Some people think it is related to the dog's sense of smell, while others think it is done by relying on its sensitive sense of direction.
