Leash Fences

How it works

1. Sneak and right click with a lead on a fence

2. Attach the lead on any other fence

Showcase

Compatibility

There's currently a minecraft bug (since 1.21.6) where the leash breaks if its stretched over a chunk border and a player dies within the chunk of the leashed entity (which is at the fence post you first connected the leash to)
