Dog owner having to move into my apartment

I find myself in a situation where we have to move out of our rental house, and move into the apartment I’ve owned since 2013.

The body corp passed a by-law in 2009 to stop all pet ownership (except fish!)

The dog is medium sized and not young – 12 years old. I have a child on the autism spectrum who would be devastated if we had to rehouse our dog.

Is there any way I can make a request to have the dog allowed to live in the unit with us for the last few years of his life?

It seems a reasonable request, after all it’s my own property.

Thanks for any advice. We have until November to move.
