What is Kieber?

Is he a new addition?!

He looks like Chihuahua/Minpin to me. Maybe with something else thrown in for good measure (Rat Terrier? Pomeranian?).

Yep. He was one of those dogs you get a "feeling" for, not cuteness or anything. Just "I cant leave this dog!".

Another thing was, even though he's cute, his constant chewing on people and resource gaurding would be a major turnoff for most people. He also humps. All fixable, but most people don't want to take the time.

Chi/Min Pin was my thought, too. Like you said, all those "non adoptable" traits you mentioned sound a lot like normal puppy things that "Joe Q Public" doesn't know how to or want to deal with. I bet he's going to thrive with you and become an awesome little dog.
