I'm for the vehicle method: make circular cuts around all four
quarters (at the joint) and then cut in front of the ears about a inch
or two and bring cut straight down the jaw line heading back towards
the field dreesing cut and the neck. The animal should have it's back facing the vehicle of choice and then start pulling forward slowly.

no nicks, not much hair, and no hand cramps. I like the no hand cramps part of it best.
