Not sure if I abu. Yesterday in the countryside I saw couple with a dog enter a field of sheep. There was no real access into the field - I think they got through a fence - and there was no public footpath in the field either. They had a large bag and sat down, with the dog running around loose among the sheep. It looked as though they were going to have a picnic. I was too far away to be heard, and a river in between us, but in any case not sure if I needed to be concerned. The sheep moved away from the dog as it ran around, but they did not run or panic. I looked it up afterwards, and it seems it is illegal to have a dog in a field of sheep unless under tight control, ie. a lead or very reliably obedient, which this dog did not appear to be. Would welcome Mumsnetters' views, especially those who know farming.
