Such a sad story...
i really hope all will be well..
but heres an idea..
u know sometimes people deserve to be fooled...
we also were residing at a place u were not allowed dogs..
and we had a yorkie 4 pounds...for years there and no one knew about it..
we had a pee pad indoors and we had the tv or radio on a little louder than normal ..just in case...
and when we took him out he would get into the big handbag go down the elevator to the car and then get out of the handbag

We were happy and he was happy and no one every knew we had a dog..
i would just tell the F*rt we do not have the dog anymore.
Out of sight out of mind !
