The moral of putting down the dog's tail
The puppy's tail is down, indicating fear and obedience. The body language of the tail is the most obvious signal to the owner, but the length and shape of the dog tail may affect the number of signals received by the owner.
In most cases, dogs wag their tails, indicating that dogs are willing to get close to others and shorten the distance. At the same time, when the dog relaxes, its tail will bend slightly downward. Confident puppies and aggressive dogs will hold their tails high.
When the owner scolds the puppy, the puppy will lower its head and tail to show fear or obedience and beg for forgiveness.
