You helped Tank, our neighbor’s dog. Your contacting him for us has educated him to be a better, more considerate dog! He does bark occasionally, but now I hear it’s because something or someone he doesn’t know is near, like a truck pulling in to his neighbor’s yard on the other side, or hot air balloons flying overhead with their gas burners turning on! But then he stops. It’s just warning barking or because he’s apprehensive. He no longer barks just to bark. You helped him understand we are not his enemy! It’s been such a relief to us! Thank you, Dana Lorraine, Texas
