So is my Shadow...she's a lab/bulldog mix. She actually woke my mom up when a burglar was in the house. Had she not, I don't know what would've happened...they were already coming down the hallway and had the light flipped on when mom finally responded to Shadow's whining. She hears EVERYTHING. We live on the backside of a walking trail and sometimes juveniles go back there to drink and have sex...she'll nut up wanting us to let her out and then she'll run to the fence and bark and growl at them, LOL
