Jurnee, the baby. NEED some input.

He looks like a mule, but a full body shot with his head up would be very helpful.

A black donkey and any dun horse could have thrown this color, I can't wait to see him shed out!!

BTW, thanks for being a part of the solution!

Those are big ears and I had to look a few times also, but I'm going to say that's not a mule. Those are the worst angles to ever judge anything about an equine. Show us a full head shot with his forhead uncovered so we can see his whorl and include all his ears and his muzzle.

I say long eared horse baby at this point but we really need a full body confo shot to give very accurate information.

As said before the BEST way to tell would probably be feet, and a tail shot as well and if he isn't a mule wouldn't it be possible that he could be a hinny??

There HAVE been successful mule breedings... quite possible he's 3/4 one way or the other!

His feet even look like a mule's. Very pointy, small and upright.

I agree, really bad pics for judging, and also don't believe he's a mule, I could say for sure w/ a good pic, but don't think so based on those pics.

In the first pics I thought he may look like a hinny, but I don't think so.

And he's not grulla, just fyi it would be dun factor, not grulla trait, a grulla is just a black w/ dun. He's definitely not grulla, doesn't look dun at all to me.

Sorry, but just for reference here is a mule about that age,

I think Smrobs is right, and he's a mule cross with a finer boned horse like an Arabian or even a POA.

From my understanding, on the rare (very very rare) occation that mules reproduce they either pass the donkey genes or the horse genes, not a mix of both. So that is very unlikely either way.
