He's a good looking dog! I can see why they'd say mali x gsd given his coat and his build. I've got one who is definitely either part of full mali and I love him so much that I'm looking into fostering and eventually adopting another!
BowWowMeow to bad your not closer to GA one organization im involved with has a pure mal female that needs a good home. She looks just like my jake too except darker muzzle.
