Our security guards, who went as far as suggesting that they would somehow "raid" our apartment to take our dog if we didn’t comply with their pet rules, seem to have had a change of heart recently. We had been walking Yoshi by putting him in a bag, then carrying him down the elevator. Once we got around a corner from the building, we would let him out. Yoshi loved his bag, so it wasn’t that big of a problem. Since the guards didn’t say anything when we carried him out this way, we figured they had calmed on the whole "No Pets" thing, even if it was still posted on the notice board.
For a month they had a warning up in the elevator about how dogs weren’t allowed in the building. One particular guard was always shouting and giving me a hard time about walking Yoshi. We even had conversations with some of the apartment "leaders" that had decreed that there would be no pets!
Now they no longer care at all. We’ve been walking Yoshi now without the bag in the evening and we haven’t been asked about anything. Considering all the hassle we had been going through, this is a nice change for us. We still keep Yoshi under control in the elevator as always, but now we don’t need the bag in addition to the leash.
This is exactly what my wife predicted would happen. She said that the security guards were simply acting tough on behest of some disgruntled tenant somewhere in the building, and that went enough time passed, they’d go back to their usual indifference. The normal security guard spends about 90% of his time doing nothing. Other than picking up packages and chatting with security guards when there is nothing else on television, they sit in their little room. Anything that compels them to actually "guard" or "police" is just an annoyance.
We just had some particularly annoying person in the building that kept the guards on task for an entire month, that’s all.
