Crazy Dogs

Some dogs exhibit a behavior called Canine Compulsive Disorder (CCD). It is similar to Obsessive Compulsive Disorder (OCD) in humans. The dogs suffering from CCD may harm themselves and annoy their owners.

Manipulating genes for medicine has good intentions. What are your thoughts on the use and development of this technology?
