One little helpful hint that we do is we ask a trustworthy neighbor to park their additional car in our driveway. We have some late teens next door (very trustworthy, good kids) and we actually throw a few bucks there way for the inconvenience. Bless their hearts... last time we went away, we came home to find all the outdoor flowers even watered. We either take the dogs or board them so I leave a HUGE bowl in the backyard. By HUGE, I mean that someone would assume that I was watering a wolf pack. Thus far, these two tips have worked for us and I hope it works for some FR’s as well.
Ha! Love the big dog bowl idea.
