I was thinking about trying one of the invisible barries to keep my dog out of the entrance foyer. This is the same entrance/exit we use to take her out for daily bathroom breaks obviously we would disarm the system before taking her out. The question is, do dogs adjust to the warning beeps of an invisible barrier or the actual physical loction of a boundry. Is it likey she would come to understand if we take her out(system disarmed) it's ok but on her own (system armed) it's a no no?
