Hello. I was reading some of these posts last night and thought it would be nice to describe Ruben correctly. He is different on each side so I don't know which side you pick to describe? He has a white chest but are tuxedos only black and white? Some of the pictures are when we first rescued him. You can see that we brought him back to health but sadly today he looks worse than back then. He has terminal cancer. Its very sad but we are making the most of the time we have with him. He is the sweetest boy ever.
