For several weeks, Einstein had sporadically started barking in the middle of the night (usually just about the time I had drifted off again). Finally, it occurred to me one night about 2 am, that he HATES water! I went to the kitchen, grabbed a measuring cup and filled it up. I went to the front door (where he stands guard against the cats parading by at all hours) -- told him to stop barking (which he ignored) -- then tossed the water on him. HE WAS SURPRISED! He tried shaking it off -- then became very submissive.
Best of all -- he didn't bark anymore that night. Or the next night. I was beginning to think I'd taken all the spunk out of him, but occasionally he'll start barking at odd things happening in the neighborhood. When I tell him to stop, HE STOPS. I keep the measuring cup on the front porch -- couple of times I've had to grab it to remind him.
It also works when he's out in the front yard and I'm ready for him to come in the house. If he balks, all I have to do is show him the measuring cup and he comes running.
I wouldn't ordinarily have resorted to threats, but that bark of his would wake the dead -- specially when it's completely quiet in the house. I don't want to reinforce his fear of water either, but I haven't had to actually get water on him again.
His new attitude toward discipline has greatly improved my life -- and consequently his. He even moves when I'm trying to get in and out the door.
I wonder if could start marketing water as a miracle cure for recalcitrant dogs.
