Thank you foxie48. I am NOT a townie and grew up with farms and farmers all around me. This happened to me once- on a public footpath where cows where always kept int he next field with gate closes. I always checked beforehand.
That day, I parked the car, and got onto footpath with my dog on leash. Checked that the friesians were behind the fence and gate in next field, then went on (footpath is about 300 metres from gate to cow field. When we were about half way to the next gate, to get access to old railway line, I saw them passing through their gate. I dropped to the other side of the hedge along the footpath so they would lose sight of me and dog- but I heard them running.
I've never been afraid of cows and know how to handle them. I turned and faced them as they came towards me, and with a very low voice, making myself as big and tall as poss- called 'OH NO- BACK' that would normally stop them. It was clear they would come for me and the dog. Let the dog off the leash and told her to go, and I managed to get to wire fence- but could not escape below as it was fixed into the ground. Managed to climb up near post to stop the wobble then over the tow rows of barbed wire and drop to the marsh the other side. Trousers torn and both thighs torn to shreds an bleeding heavily. Up to my knees in the marsh, I managed to get to other fence onto pavement by roadside and back to my car- took me about 1 hour. And found my poor dog cowering under the gate, she had managed to put half her body under, and rest still in field. Cows had gone, and she was miraculously not injured or trampled.
I contacted the Police, the Ramblers Association and the farmer. The biggest milk provider in the region, and a very aggressive and rude man (not just to me, his reputation was well-known). Had I not known how to handle the situation and not let my dog go, I am sure I would not be here to tell the tale. The farm worker who had put the effers in the field in the morning had not closed the gate properly.
