Chasing Tails
It’s fun to see dogs trying hard to catch their tail. It’s a usual sign of playfulness for them. When they do it too often, however, it could be a sign of behavioral problems. When they chew on their tail, it might indicate allergies or problems in their anal glan. It could also be an indication of OCD.
Licking
Dogs would lick you to tell you they love you. It’s a common behavior in dogs to show their love. When dogs lick their humans, they can also taste the nutrients on the skin. If you think the licking is becoming too much, there are always methods to train them correctly.
