Strong “group” willingness
Dogs have a solid natural intention to join and become part of a “group”. This can be traced back to the old days when dogs formed groups to defend themselves effectively from outside animals to survive.
Moreover, the establishment of an order of superiority and inferiority within the group can determine which dog has the priority of feeding and reproduction.
In the wild, dogs fighting with each other will cause injury easily, which is not conducive to survival, so a series of behaviors have been developed in the dog’s society, including body posture, glare, growl,ing and other expressions to resolve conflicts, determine the superiority and inferiority, to avoid fights and bloodshed. This kind of body language and facial expressions has become an effective communication tool to express ideas and reactions.
This “group” behavior makes dogs easy to become close human companions. Dogs love to socialize and enjoy human companionship. Older people and children have more time to spend with dogs and therefore often develop a special bond of intimacy.
Male dogs have a strong desire to define their territory by leaving their scent marks by peeing. To secure their territory, male dogs urinate very frequently and “mark” where other males have left their mark, attempting to overpower the scent marks left by other dogs with their own scent.
In addition to urination, dogs also mark by digging into the soil through their hind limbs, as the sweat glands of their hind paws can also be used for scent marking.
Sometimes, dogs will roll on objects with strong odors to get those odors on their bodies and reinforce their own scent. Common examples are pig and bird feces and urine, which are unbearable odors for humans, but which dogs often use as their markers.
The dog’s sense of smell is very sensitive, and its olfactory brain, olfactory organs, and olfactory nerves are extremely developed.
The dog’s nose is long and the nasal mucosa is covered with olfactory nerves, which can sniff out organic acids diluted by one ten-millionth, especially sensitive to animal fatty acids. A dog’s sense of smell is 1200 times better than a human’s.
Usually, dogs reach initial recognition by sniffing each other. Sometimes we see two dogs who don’t know each other sniffing each other as soon as they meet, which is the first step of socialization between dogs and mostly circling and sniffing each other.
Fighting for territory
Dogs are particularly territorial, and it is instinctive for dogs to defend their homes and their habitat against invasion by humans or other dogs.
At home, the dog sees the owner as the leader and will naturally take charge of the group’s defense. If a stranger is accepted by the owner, the dog will also accept the stranger. When the owner is not around, the dog will take over his position to take responsibility for defending the territory, when their behavior will be very different, even a small, quiet female dog will show “territory aggression”.
