Last resort, You might try air soft pellet? One of your buddies may have a rig. Downside, it will take a smart dog about three episodes to associate you to the event, as a result dog will not like you! And exactly to your point it is a draconian step when it is actually the owner who needs the air soft application! I agree with one of the previous posts, befriend the hound so that she sees you as a buddy then you can train her if you will to follow your instructions. Be firm friendly and very consistent and she will soon comply. When you see her out you might approach her first thus giving the pup the attention she craves at the same time negating her need to invade your space to achieve her goal of wanting your attention. Just thinking outloud BP.
