Barking doesn't seem to be too common in my house either. Ginger is a lot more quiet than Hammer, but that could be because she's new to the house. She only barks when she hears a noise outside and generally it's just one bark (warning?). Hammer's a lot more quiet now that Ginger's here, but he still barks a few times per day, usually only when playing rough with daddy or when we leave.
Their usual noise is a whimper or the woo woo song. Neither makes a sound when they need to go outside, they just go to the door. We are trying to teach them to ring the bell for those times we don't see them at the door. :rolleyes:
