What is my staffy crossed with? Unusual markings

Hey guys, i hope this is in the right section.

My sister in-law has had a staffy but it has really unusual markings on its face for a staffy.

Hope somone here could shead some light for me here is a pic:

Kinda looks like subtle Rotty markings to me but I'm not any good with guessing things like this! S/he is gorgeous by the way

Could be some Dobermann or German Shepherd Dog too, gorgeous looking dog all the same   

Could be rotty or gsd quite similar to my parents first dog that was gsd/black lab cross

I would say German shepherd/Alsatian x

I say rotti or GSD as well hard to say for sure though. Great looking pup though   

Beautiful pup my first thought was rotti, but I'm rubbish with guessing crosses xx

I though GSD too, hes cute   

how old is pup and do u have anymore pics u can post its hard to tell from the 2 pics u posted but is going to be a stunner whatever he/she is mixed with!

Black and Tan, just undesirable if ever showing and a cross somewhere, could be way back.

Mate he looks a cracker

Pfff, I've no idea but what I do know that he /she is a beauty

id say definitely rottweiller and maybe german shepherd

Hi ya Anbuma, come say hi to everyone here:-

How old is the dog? He could have a bit of otherTerrier in him eg Manchester or Miniature Pincher, maybe a bit of Border? Depends on his/her size .

Id say GSD although gut instinct was rottie. has a very athletic frame and very spitz lending itself to the GSD leaning. also looks just like my two staffy cross sibes at that age but with gsd markings. Rotties are more heavy set and more bulky muscle wise.
