I have a nine year old Rhodesian Ridgeback who likes to bark at hot air balloons. My house is directly under the flight path and he can hear them coming from miles away and can watch them almost down to the ground when they land because we are at the top of the hill. They usually go over between 6.00 and 7.30am and he barks continuously while they go over. Sometimes there can be 3 or 4 go over in a morning. My neighbours are good about it, but tolerance has its limits. It is especially bad on the weekend when everyone is wanting to sleep in. They are unpredictable, as we may go days or weeks without one and then they can come every day for a fortnight. I can't keep him locked in while they go over, as often I have long left for work before they appear. When they go over, I call him in and give him a bone or liver treat to get him in the door. I know this rewards and reinforces his barking, but I have to stop the noise before we get reported to the council. I have just heard about clicker training, and am keen to apply postitive training methods to try to solve this problem. Can you please help? He also barks at the postie and if someone walks by the house, but does not bark for 'no reason'. Apart from hot air balloons and the postie, he might go days without barking.
