Chasing Tails
There is a very good chance that you have seen your dog go around in circles to chase their tail. It is a common sign of playfulness in dogs. Doing this too much might mean health or behavioral problems, however. A dog that chews their tail could also mean allergies, gland issues, or even OCD.
Licking
Licking is common behavior in just about any dog. This is how they like to show affection. A dog that licks you is the equivalent of a human being telling you they love you! Dogs are also fond of tasting the nutrients and minerals in our skin. However, too much licking can be stopped with proper training.
