Could your pup have OCD?
If your dog exhibits incessant tail chasing, he just might suffer from what would be considered OCD in humans.
MSNBC reports that Finnish researchers, led by Katriina Tiira of the University of Helsinki and The Folkhälsan Research Center, found thatdogs with anxious behavior
such as tail chasing and humans with obsessive-compulsive disorder may exhibit similar behavior for similar reasons.
Whereas humans with OCD tend to wash and rewash their hands and check that appliances are turned off, dogs with this condition chase their tails, bites their hinds legs, pace back and forth, or nip at invisible flies.
