I disliked the tail docking ban. But I now think the long whippy tail looks right on a GSP. So far that long whippy tail while it has banged around has never been a problem and injured in any way. But Blitzen also has never really hunted in thick heavy country, just bits of it.

As for sheep tail docking, dogs don't have wool, and don't get fly strike and maggots, and have flesh rotting off them like undocked and non-maintained sheep might.
