prompter: Why does my dog spin around in circles before he lays down?

assistant: While behaviorists are not certain about the exact reasons, dogs usually spin for the following reasons:
1. Survey their surroundings: Before dogs were domesticated, they would need to keep an eye out for predators before sleeping. Spinning around allows them to quickly see and smell their surroundings before rest.
2. Make a den: In order to make their sleeping spots more comfortable, dogs would have needed to clear tall grass, brambles and rocks. Spinning around would allow the dog to pat down and brush aside any obstacles.

Notice that these reasons are no longer relevant to modern dogs, who usually sleep comfortably inside safe houses. However, the instinct to spin around was trained over millions of years and so continues to affect their behavior

prompter: Does humans also have that kind of behaviour traits that are no longer required but still exist ?

assistant: Yes, humans also have behaviors that are no longer necessary but still exist as a result of evolution and cultural practices. For example:

Fear Responses: Humans are wired to respond to certain stimuli such as heights, darkness, or loud noises with fear. These responses were once critical for survival, but they can now be maladaptive and interfere with daily life.

Eating habits: Our ancestors had to store food for long periods in their bodies, but in today's world, food is readily available. This has resulted in overeating and food cravings.

Aggression: Aggression was once an essential survival tool, but in modern society it is often seen as a negative behavior.

Sleep patterns: Before the invention of artificial lighting, people had to sleep when it was dark, and wake up when it was light. Nowadays, artificial lighting and modern lifestyles have altered our sleep patterns, but many people still have a natural inclination to sleep when it is dark.

These are just a few examples of behaviors that are no longer necessary but still persist in humans, which can be traced back to our evolutionary history.

assistant: Dog behaviorists believe that a dog’s need to perform the bedtime ritual of turning around in circles before lying down is inherited.  Canine ancestors, such as wild wolves, did the same thing, and domestic dogs retained this genetic predisposition. Turning in circles before lying down is an act of self-preservation in that the dog may innately know that he needs to position himself in a certain way to ward off an attack in the wild.

prompter: Can you mention other behaviors that dogs may exhibit that are retained from genetic predisposition?

assistant: Yes, here are some other behaviors that dogs may exhibit that are retained from genetic predisposition:

1.  Barking: Domestic dogs bark as a means of communication, a behavior that is inherited from their wild ancestor, the Gray Wolf.
    
2.  Digging: Dogs may dig for various reasons, including foraging for food, burying bones, or creating a cool place to rest. This behavior is inherited from their wild ancestors, who would dig for food and to create dens.
    
3.  Chewing: Chewing is a natural behavior for dogs, and it helps keep their jaws strong and their teeth clean. Domestic dogs inherit this behavior from their wild ancestors, who would chew on bones and other objects to sharpen their teeth.
    
4.  Herding: Some breeds of dogs, such as Border Collies and Shetland Sheepdogs, are known for their herding instincts. This behavior is inherited from their ancestors who were bred to assist farmers in controlling and guiding livestock.
    
5.  Marking territory: Marking territory is a natural behavior for dogs, and it is often seen in male dogs, who will mark their territory by urinating on objects. This behavior is inherited from their wild ancestors, who would mark their territory to deter other animals from invading their space.

assistant: Dogs will roll on the lawn or carpet, rubbing their backs or they will rub up against furniture when they experience happiness or content.  Most often they will do so after eating an enjoyable meal.  This can be likened to how a person will experience stress release and enjoyment from a massage.

assistant: Other behavior like this, in dogs for example following the alpha male.

prompter: When asleep, my dog sometimes makes noises such as soft barks or cries. What does this mean? Could they be dreaming? If so, do we have any idea what kinds of dreams they have?

assistant: One theory is that this helps dogs to fall asleep.

prompter: Are there any other potentioal reasons for this?
