Please let me out!

When driving through Harpole, I came across this farmyard wherein I spied 4 dogs, this being one of them who seemed to be saying 'I would rather be out there with you'!! Another one jumped on the wall (see extra photo), all except one was friendly towards me. According to a local passer-by, they are working dogs and well looked after!! I believed him!

I only know what I 'herd'
