Can you please help me identify his breed?

Doberman or rottie definatly one of them or mabye both

he moght be part doberman, part hound, or part GSD. the thing is there are alot of dogs with those markings

I know exactly what he is! He is a German Shepherd mixed with a Black Lab! HE seems really sweet! And very cute!

I see GSD mix... its hard to tell what else may be in him - he's a good looking dog and looks really friendly, hope he finds a home :)

he is a GSD ..but mixed with a collie maybe. he had the ears of a collie but looks like a GSD hmmmmm tough case

look like part of german shpherd mix australian shepherd.

Looks like a rottie dobie mix to me, cuz of the coloring, build n it's muzzle.

He looks like a german shepherd/ doberman pinscher mix. That would explain the short coat, ears and markings,

he looks like a doberman/collie mix, Iv seen that mix before and it looked just like him!

Ooh definitely german shepherd and rotwileir( sorry bout the spelling no idea how to spell second breed). Look at the face pattern!

i would also go with collie , but it got a wide jaw bone , like my 2 gsd x staffies , , if it has big pear shape ears , and a few with patches , i would go with collie, , if the ears are just triangles , i would say gsd x " bull terrier type " staffie , blah blah

it is a lil tricky for me to say with just face pics , ,

Aw, what a darling dog. :) Would adopt him if I had the money.

He actually looks to have the coloring of a rottweiler, but the facial structure of a german shepherd. I do agree that his ears look like the ears of a collie. He could have several bloodlines...I wish I could help more.
