Why does my dog wag its tail?
A dog uses its tail wagging, facial expressions, ear position, posture, and vocalization to communicate. Puppies start wagging their tails when they are about six or seven weeks old, as they begin to interact with their fellow littermates and humans. However, a wagging tail is not always a sign of friendliness: an aggressive dog might hold its tail high and wag only the tip, while a submissive or scared dog is more likely to hold its tail low and wag it stiffly and a happy dog may wag his tail to and fro
