There is somewhat less choking hazard with a halter, but there's a lot more danger of injuring the neck because of the leverage a halter can exert on the head (this is what makes it such an effective tool for leading and restraint). Even on a high or low line, a tethered goat has enough slack to forage a bit and to lie down comfortably. This means he also has enough slack to put a fair bit of force on the rope when he hits the end in a panic situation. A halter will cause his head to suddenly snap back or jerk sideways, which could break his neck or at least injure the vertebrae. The worst that is likely to happen with a collar is that he will get a bruised windpipe.
