I thought the fences had to go 18" underground to be sure. Let me check that.
Various search results say 1m, 36" or 48" high and some say 6" deep where some say bend the bottom 6" outwards along the ground and some say you should bury 12" of it across the bottom of and up the garden side of a 6" trench.
They dig deeper than 6". Trust me on that.
But are they smart enough to start digging far enough back from the bottom of the fence to avoid the bit that's been turned up?
