I wouldn't say farmers hate dog walkers adeucalione
Famers don't like people who
-drop litter
-leave their dogs crap all over their grazing fields scoop, spreading Neospora and Sarcocystosis
-let their dogs chase livestock usually with devastating consequences
-Steal trees, walling stones, large amounts of firewood, holly at Christmas, apples and occasionally (and thankfully very rarely) baby lambs. yes it may be a public right of way but these things are owned by the farmer just as much as your BBQ or bike in the back garden is owned by you.
-light fires, portable bbqs, camp without permission (if you asked we would generally say yes!)
-razz everywhere on off road bikes
- break into fields close to the footpath to play in streams/ woodland etc because it looks like fun. Yes it might be, but theres also an endangered species of primrose/ crayfish in there that you just trampled on. We get paid to protect them, thats why it is fenced off.
We have vast expanses of land that are not fenced at all, one day our cows may be a mile away from the footpath, the next they might have decided to lie right on top of it.
Nearly all of our land has public access right across it, often right through the middle of a field. We haven't chosen where the footpaths are, we also wouldn't expect someone to stick rigidly to them if they want to avoid our cows if they happen to be in the area.
Please bear in mind that if the fields weren't being farmed they would just be turned into housing/ factories/ waste land. The countryside only looks pretty because farmers keep it that way - you wouldn't have nice places to walk your dogs if that wasn't the case.
