Near me is a nature reserve called Wicken Fen and it has an off road cycle path running through it. I'm all for the give and take and 90% of the time have no problem with dogs though I must admit it does grate that so many folks drive miles to get there, clogging up narrow lanes just empty their dogs in the area.
It's also a very well used cycle path and yet many dog owners seem surprised to see someone on a bike. I can never work that one out! Then there's all the $hite everywhere- often in little bags lobbed into hedges. And so many dog owners seem to have no idea about the countryside- risks to ground nesting birds/ livestock etc.
Most are fine though but a minority often don't seem to have any control over dogs. Just today there was a couple with 7 or 8 small dogs, none on a lead, on the cycle path on a nature reserve and completely out of control. Bonkers really. These are the types who seem to relish a confrontation for some reason, but I'm long past interacting with any of them. I just slow right down or stop, ignore them walk past and then carry on with a sigh.
