I trained mine to guard my crop... best security ever... they know better than to mess with it at all, its easy, just surround your plants with posts that are at most two feet away! they will mark the post and protect your crop, especially if you put up a little fence, and show them that no one is allowed in there but you... i.e. bringing them to the boundary and making them stay right there, not allowing anyone beyond the barrier, and training them to know the smell of it.
