Humans aren’t the only ones to suffer from obsessive-compulsive disorder. Dogs can suffer from the disorder as well, with particular breeds compulsively chewing their feet, chasing their tails or sucking blankets.
Now scientists say they have identified several of the genes that trigger the behavior in Doberman pinschers, bullterriers, sheepdogs and German shepherds. Four genes, CDH2, CTNNA2, ATXN1 and PGCP, involved in the communication between brain cells appear to play a role in dog OCD, researchers report February 16 in Genome Biology. The results could be used to better understand the disorder in people.
