He's got an overbite. It looks odd, but I have seen enough pictures of healthy deer with ugly overbites to know that it's nothing that will ever jeopardize his health and/or development. Don't convince yourself that this is an animal that should be "culled" due to injury, disease or deformity because he's just fine. Not sayin' that's where you were going with this discussion - just giving my .02 before the next guy chimes in and says that this deer is starving to death and needs to be euthanized. I have a buddy who's shot about a half-dozen sub-100" yearling bucks in a row, because he's convinced that he's doing the whitetail world a big favor by eliminating deer with "bad genetics" that would "never amount to anything." Maybe if one or two of them would actually get to experience their second birthday, we'd actually know what kind of antlers they were capable of really growing. I got off-track there. It's late, and I'm rambling. It's an overbite. You see that every once in a while. He looks fine. Good luck.
Don't worry, he's not on my hitlist. Anyway, besides the massive overbite, he also has dark patches all over his body, and his coat is really, really loose. Only reason I'm asking is because I've never seen that before.
Not even sure that is an overbite. And I am sure that the spots is just him growing in his winter or loosing whats left of his summer coat. Nothing wrong with him other then he needs couple more years to grow!
The loose coat seems to be in direct correlation to his body position. The dark patches, I would agree, is coat transformation. The overbite, may be slightly over embelished based on the frame, but would have to see more pics to be sure. He looks like a decent young buck to me!
