Canines with CCD and humans with OCD typically perform repetitive behaviors. In humans, excessive hand-washing and endless checking that appliances are off or that doors are locked are common. In dogs, common behaviors are flank-sucking, blanket-sucking, licking and tail chasing. In both species, anxiety disorders can interfere with quality of life and daily routines, and can also cause injury as skin is chafed and rubbed raw by licking, washing, or sucking.
It’s no big surprise that the brains of affected individuals have similarities. After all, it has been known for a long time that members of both species exhibit related symptoms and respond to the same medications, and that there’s a genetic basis for these disorders in dogs as well as in humans. Still, the discovery that brain abnormalities are also alike adds to our understanding of the parallel nature of anxiety disorders in us and in our best friends.
