Assists in Movement
When your dog is simply walking around, he doesn’t really need his tail to help with movement.
Helps with Balance
Besides acting as a counterbalance when your dog is moving at high speed, a tail is also useful for balancing on tricky surfaces.
Shows Mood and Emotional State
Your canine’s tail isn’t always busy helping with movement and balance. Most of the time, as our pets go about their daily lives, their tails are active in other ways.
Indicating their emotional state with their tail is part of a dog’s communication.
Spreads Their Scent
A dog’s tail-wagging behavior also serves the purpose of spreading its scent. There are two sacs, called anal glands, located underneath a dog’s tail.
