Dog training

I went for a stroll up the farm to celebrate finishing one batch of marking and being approved for the next batch. Since the sheep have gone the dog training classes which used to be further up the lane have move to the field just past the new redundant lambing shed. I was taken with the bag this lady had and the pole she was carrying but even though I watched for a while I'm no better informed about the paraphernalia in those pockets. Perhaps my doggy-owning friends might know?
