Found some fence wire where it shouldn't be; not sure how it got there, but the mower found it, and made what looks like a crown of thorns

It's a pretty intelligent dog, and "soft" - tone of voice is pretty effective for correction. Very different than an airedale, where you sometimes have to physically intervene to get them to stop doing something - like killing a littermate, or dragging the cat off with puppy enthusiasm.
