2. The dog's defecation center has not developed enough to defecate on the move, so we should give it a certain defecation time. Dogs usually defecate within 30 minutes after eating.

3. Dogs like to chew bones. This is also the habit of biting prey in the original ecology. When feeding, we should always give it some bones or chewing gum. But be careful, it is best not to use chicken and duck bones, because those bones will form spikes after being crushed, which may scratch the dog's esophagus and even pierce the dog's intestines.

Dogs have unique self-defense ability. After eating toxic food, they will cause vomiting reaction and spit out toxic food.

5, dogs are generally in a shallow sleep state, and they can wake up with a little movement, but they also fall asleep. Dogs are not easy to wake up after a deep sleep, and sometimes they talk in their dreams, such as barking and moaning, accompanied by convulsions of limbs and shaking of their heads and ears. When sleeping lightly, the dog is prone, with his head resting between his two front paws, often with one ear close to the ground. When you sleep, you often lie on your side, spread out all over, and look very comfortable.

6. A dog will never attack an opponent who falls and shows his belly. Sleeping upside down means that the dog is at ease or trusting, so that people can see or touch its belly. Dogs like people more than their peers and have a strong protective heart for their owners.

7. The dog's code of conduct for strangers is to judge the strength of his opponent according to the height of his sight. When a stranger approaches, the oppressive feeling of coming down from above will make him uneasy. If you keep a low profile, he will accept you. If it is lower than the height seen by its eyes, it will make it feel more secure. The dog's weakness is on the right, and it will make actions to protect the right. When it is cornered, it will lean its right side against the wall and its left side will face the enemy. The dog shows its belly to others as a sign of obedience and surrender.

8. When a dog is sick, it will instinctively avoid humans or other dogs and hide in the dark to recuperate or die. This is an "atavism". Because the ancestors of dogs live in groups, if there are sick or injured dogs in the group, other dogs will kill the injured dogs to avoid being dragged into the water or suffering after falling behind. Therefore, if the owner finds that the dog is depressed after hiding, it is best to seek medical advice in time.

9. Dogs have territorial habits and occupy a certain range to protect themselves from other animals. They use anal gland secretion to make feces have a special smell, sweat secreted by sweat glands between toes and pictures of scratching on the ground with hind legs as territorial markers.

10, dogs prefer to live with people or other animals and don't like being alone. Animals such as cats and chickens can live in harmony with dogs and be protected by dogs after a period of time. Dogs are particularly afraid of loneliness. Try not to leave their dogs alone for a long time.
