You can eat the bad smelling hogs - the smell doesn't affect the taste - just be ready to face the wrath of your significant other when you stink up the whole house while you're cooking it. Here's a great video on how to dress out a hog in 10 minutes or less. You don't even have to bother with gutting them. The guy in the video, Glenn Guess, is a legend in the hog hunting community. He's really well known for being able to call in hogs using sounds that he has developed himself.
