Here are some pictures of him from different views, the most traits that make me think he's not 100% are the graying of his eyes where the yellow goes through and the yellowing on his back. If he's possibly a "dinker" what do you suggest pairing him up with to prove anything?

I'm unable to get any history on him from his previous owner.
