I researched this and the consensus is that their is no definite answer, not enough research exists. Most think it is due to removal of the animal too early from his parent. However, it seems more common in specific breeds (like my Dobie). I was very curious about this behavior because my Doberman and I were separated for about 8 months from my wife (work related) and our other 2 dogs and the behavior disappeared while he was living with me. A month after we were back together the behavior started back up again. I wouldn't be to concerned ... he shows no other strange behavior and seems happier with the family reunited.
