And if you chose to rehome him, do not take him to the SPCA or Humane Society since a big dog's chance of being adopted is slim to none. You need to find a home willing to care for him.

I wouldn't want to be in your situation.
Catnapper is absolutely right. I would try my hardest to find him a home on my own and soon. I don't like the impression I am getting of your dad and what he might do. What a horrible situation.
