How are dogs' compulsive behaviors related to those in humans?

Via Tufts University, "Newly identified genomic causes of severe compulsive behavior in dogs could further understanding of human OCD."

Basically, it looks like the gene responsible for human OCD is more or less the same as the one responsible for CCD, or canine compulsive behavior. Any time scientists are able to use this "comparative genomics," it tends to be fertile ground for finding new possibilities for treatment.
