Not very easy from that photo (and I'm definitely no expert!) but it looks as though it could have a bit of malinois it in. I would say a crossbreed, whatever it is!
Looks like some sort of GSD cross. Fur looks too thick to have Mal as main breed IMO. Ears look somewhat floppy, right? Maybe GSD/Lab or Golden or something. Black muzzle certainly screams GSD cross.
