Official unofficial dog walking paths

A walker explores a riverbank looking for an interesting walk, another sees the flattened grass and follows the track and so an unofficial path is born. There's a fair number of these in Euxton and doubtless where you live too. What do we think about them? It's handy to have paths linking to other paths but I wonder what the land owners think when their barbed wire fences are persistently breached.
