I found this interesting and informative, I hope you agree.

This is what I found on RD.COM:

Dogs have tons of strange quirks, from spinning in circles before they poop to kicking up the lawn afterward. But among the weirdest: chasing their own tails around and around.

It might look like a strange activity to humans, but tail-chasing is a way for dogs to burn off some steam. In most cases, they’re whirling for one of two reasons: They’re bored or they’re stressed, says certified dog behavior consultant Russell Hartstein, founder of Fun Paw Care.

If a dog doesn’t have anything (or anyone) to play with, it might need to entertain itself—in this case, by playing with its tail. On the other end of the spectrum, the behavior could be a warning sign that your pooch is anxious or stressed. “We call these displacement behaviors, similar to a human twirling their hair or tapping their foot,” says Hartstein. “They seek to do self-soothing behaviors.”It’s normal for dogs to chase their own tails every now and then, but watch out if your pet is doing it every day or it seems to become an obsession.
