Well according to NG these were "guard" dogs that could attack if you were a "stranger." There was a clip of the dogs in a previous board and well ... they didn't look like "mean" dogs ... sooo they probably were chill. No reports of neighbors hearing any barking or whining
According to VF's husband he just kept trying to call her & calls went straight to vm. He never mentions trying to call PS but went back home on the 14th to wait for PS to call back re: VF being @ hospital with AS, which we know was false.
Some dogs, even laid back ones, are reactive to strangers when walking on leash. Some bark when strangers come, but quickly warm up or do not attack. Although most of us would not call the family dogs "guard dogs," people define this differently. My chi/lab who weighs 20 lbs is a super "alarm dog." In any case, it seems the dogs were bypassed completely in entering the house.
What I do find strange is that dogs would not bark whine, scratch at doors to be let in at night. Outside enclosure with food? Treat-lured in and out of some sheltering space apart from the "action?"
If perpetrator/s attained info. on household or they "cased," then dogs' reactions and routine might have been a consideration in any planning. Otherwise, an accomplice or DW, the alleged perp, knew how to treat-lure dogs to comply with directions, knew by the look of the dogs they would not be a problem.
Would things have gone differently if two Rotties, Dobies, or my Chi in the yard? My Chi has xray hearing and any screaming or thumping, possibly the smell of strangers would have him barking, whining, scratching to get in. He barks from inside our apt. building at people talking near a block away outside and every time the downstairs lobby door opens or shuts. How would a perp know these dogs not like that? Maybe dog area far enough away from the house.
If victims kept upstairs, curtains and windows closed, maybe dogs none the wiser about goings on. Still, some arrangement likely had to be made for the dogs overnight and into the next day.
Dogs want food, water,walkies, daily habits observed. They react to change in routine. They might run about looking for guardians, bark when people pass to alert them that something is amiss.
Perpetrators are usually more afraid of barking than anything as barking dogs inside or outside a house attract attention.
What preparation did perps make to prevent barking? Or how did they know there would not be barking?
