Thread: Barking German Shepherd

Sounds like the dog is stressed at being left alone. Before you try the collar thing get the owner to record there voice. Usually at a dinner party or on the phone. Then get the owner to shut the dog in it’s space and play this recording while they are at home.
Go in and out, gradually leaving for longer and longer periods of time. Usually over a long weekend.
They also need a safe space a wire crate with a blanket over the top and three sides to make a cave. Leave the dog in here. Obviously if it’s hot it needs access to water. Play the recording from the next room.
Try this. You must tell the owner to be strong and not go in when ever it barks. But just move near the door and back away again. If it still barks the the spray collars in line with the recording should show results. A video recording of the room while the owner is out will also be educational to the owner on what the dog is up to while there away. You could then maybe set up a phone call to talk to the dog through a speaker.
I’ve seen this done here in the UK with very good results. Worth a try.
