I think I'm certain situations horse owners should be legally obliged to pick up their horse's
tit, as dog owners are.
tit in a field? Fine.
tit on a road? Not overly arsed.
tit on the footpath beside a road? Not ok, clean it up.
There's a riding stables near us. Several of the owners ride their horses on a couple of sections of footpath, and there is regularly piles of
tit on the path. I've witnessed wheelchairs, pushchairs and small children on bikes and scooters having to move into the road to avoid it. Apparently it's OK though, because it's "just hay"
There are plenty of other places to take a horse that don't involve them shitting where people are trying to go about their business.
