Think your pup’s wagging tail means he’s happy to see you? Maybe. Or maybe he’s just not into you. Here is how dog behaviourists decipher what a dog’s tail indicates.
Full body wag
You probably see this wag when you come home from work every night. Your pup welcomes you with a tail wagging in a big circle. You’ll also see him shaking his entire body in a loose way, accompanied by a submissive grin or a soft open mouth. “The more swaying and wiggly motion closer to the head of the dog, the friendlier the dog is,” notes certified dog behaviourist and trainer, Russ Hartstein.
Fast and shaky
When you see a fast, vigorous, almost shaking tail on a dog, take it as a cue of tension and/or hostility. The dog could spring into action at any moment. “This is a highly aroused dog and should generally be avoided until it settles down,” cautions Hartstein.
