OP, could it be that you're missing the common sense in your friends decision to hump dogs? You already mentioned he is on the verge of destitution, the last thing he needs is a human girlfriend who will demand time and money that he OBVIOUSLY can't afford. Can you feed your girlfriend a can of Alpo and expect her to put out on a regular basis? No, you can't. And I'm not just saying that. Women are complicated, needy beings and have NEVER been accused of being "man's best friend." So, I digress; try to see the brighter side to poor internetfolks having sex with animals.
