Lifting and wiggling of their eyebrows
For a long time, people have associated tail wagging as a form that dogs use to communicate. However, facial expressions can be even more powerful. Movement of the left eyebrow or ear is a sign that means that the dog approves the person they are in contact with, or the action that is being performed.
Leaning on you
When you lean on another person, you know that person will help you and comfort you. Dogs do exactly the same, they lean on people they love because of the affection and security they feel when they are with them.
