Prepare to feel terrible about every time you've ever laughed and encouraged a dog that was chasing its tail, because it turns out that is basically like clapping and cheering on someone struggling with OCD, except that chasing a tail is way cuter than turning the lights on and off a set amount of times before leaving a room. A recent study in the journal PLoS One
suggests that tail chasing could be a symptom of a canine analogue to obsessive-compulsive disorder (OCD)
. Truly, this is the saddest of all mental illnesses, with the possible exception of the obvious schizophrenia exhibited by every cat, ever, anywhere in the history of time.
