Just in case you couldn’t perceive of when the Sanitation Engineer was upon foot these geniuses above will provide you with the alarm you’re sure not to miss. Yes, even those hard of hearing will notice when the perpetrators of garbage pick up are around the corner with their lovely voices. Don’t worry about guarantees as these alarms are set for a lifetime and no batteries are required although a biscuit would be appreciated. The Dog Alarm also works with Mail Deliveries, Uber Drivers and any person near or a bit far. So rest assured (well maybe not rest) dog alarms really do work even when you really don’t want them to.
