8. Turning on itself before laying down
As we mentioned earlier, dogs are distant relatives of wolves. Spinning several times on their own axis is their way of checking their surroundings and making sure that nothing dangerous is waiting to jump out and take them by surprise. Of course, in the case of domestic dogs, this is mostly an inherited reaction. This is also a way to sort of test the waters and make sure their new napping spot is comfortable enough to sleep on.
