That's crappy! But at least your parents are going to take care of him, so you can still see him.
I would just lie to the apartment people

They will never know...When I moved in with my hubby before we were married, he lived in apartments that didn't allow dogs at all, and I took Duke with me anyway. There was no way I was moving without him. We lived there for about 3 years, and never got in trouble.
