I don't wrap anymore. Used to always wrap or use
shipping boots, but I was hauling in an old straight load 2 horse. More often it
was another horse with them, some how clipping or banging in to the others legs
that caused injury. If your horse is an excellent hauler, does not
scramble or kick in the trailer, I'd not wrap. I personally don't feel they need
the "support" of the wraps for trailering unless they already have some problem
or lameness issue in a leg to need wrapped.
But, some do believe in wrapping legs., but since
you are not along to check the wraps, I'd leave the legs bare.
That trip from NM to LA is about 1200
miles...and the commercial hauler is saying 4-5 days? Must be taking the
scenic route
