Hi Kamz119,
I think the NSW govt made changes to the Strata Schemes Management Act for easier pet ownership a bout 4 years ago. Our Strata scheme adopted a bylaw where pets were allowed with permission from the Committee. I think there needs to be a very ” good ” reason for a pet to be denied. Now a medium to large dog such as a German Shepard may be considered a ” good reason ” but the fact that your puppy is necessary ” medication ” I place it in the same category as a seeing eye Dog and you should have special consideration. I have a mate who needed a companion dog for his PTSD and he can bring the Dog into a cinema with him. I think by presenting all the precautions you’ll take and make in keeping your puppy as she grows and the fact she is a ” treatment ” dog you have a pretty good argument for keeping her.
Good Luck
