Not for anything but a horse doesn't even move like a deer. I'm not a hunter so I won't be condeming this guy but how big does he thing deer get? A moose maybe...but a deer????
As I said I don't hunt but I have seen plenty of deer and they aren't even close in size to a horse.
Like I said about a goose and a swan, you can't mistake them. Mistaking a horse for a deer is unacceptable.
