my dog occasionally busts his tail open in the car. for the first couple months i had him i wondered why i would see tiny specs of blood on my computer screen occastionally. then one day i noticed the very end of his tail is basically hairless and to me almost looks like scar tissue (from being broken open repeatedly). it still happens occasionally, but not enough that i would consider docking him. if it got to be a regular occurrence, i would consider it. i have worked to keep his spinning down to a minimum like making him go down when i'm just parked in a lot report writing or if i'm meeting with another officer...Jacob Tallmon said:
