Gees !, Building Management can be SO inconsiderate at times...
I can fully understand your DH's point of view, AND yours as well !
OK, let's try this from another angle...
How about getting that Nylon Rope (about 20' or so), putting a
Snap Hook on the end of it, and tying the other end INSIDE
your porch/house.
This way, you can get the harness on her, snap the XXlong leash
on that, and just set her outside, which would limit her movement
to the area around your door. You might even prop the door open
to allow her to move in and out on her own. Or, you could just close
the door (that won't hurt the Rope) and just let her be outside for
a while on her own.
This way, you can pull everything back inside, still have it immediately
ready for re-use, and and Management won't have anything to complain
about. Admittedly, you'll have to anticipate her need to potty, but,
regular "outings" will probably get her in the mood to do it outside.
It may be that your presence is limiting her willingness. Some Dogs
just like to do that when someone is looking
(Point of View)
That "I don't want you to watch me potty", implies Shyness !
Shyness is a LEARNED trait, and implies self-awareness.
And WE have the audacity to call them "Dumb Animals", HA HA HA !
