LOL - Ninja and Lani have a very similar bark/howl. It drives me nuts sometimes! I think my dogs have learned that noises that come from the computer area are not real and stopped paying attention to it. They come running and give a confused look and then go back to whatever they were doing.

Are you sure it was Hilo that started it? I think it might have been Lani.
And he's still barking.....
