I do have a dog, but she's a bit keen and not always very attentive, so moving sheep across open moorland and into a (small) trailer would be beyond her.
I got the first batch loaded today though.

With a lot of slipping and sliding and unhitching and re-hitching and grim determination, I managed to get the trailer to the gateway by going across the moor rather than along the track. A few hurdles, a bucket and a helpful assistant meant I was able to load them with very little effort. Once I'd got there!
Snow due tomorrow evening, followed by yet more rain, so very relieved to have them back home now.
It is a beautiful place, Mowhaugh. The moors centre is just up the road and round the corner from my fields.
