Staffy cross?? Questions

Hi, we're due to pick up a Staffy cross from Dog Rescue in next few days, we're told its a cross, any ideas??

Now, I suspect there should have been a piccie with that....

Eh, yes
Still working on that bit ........!

I managed to open the photo by right clicking on it and selecting open image in a new tab. Its hard to tell with only being able to see her head. Are you able to get a full body pic?

Her head kind of looks English Bull Terrier-y. I'd guess Staff x EBT.

Thanks for replies.
I'm going back to see her today so will try and get full body pic. My first thoughts were EBT x Staffie, but still bit unsure. Will get full pic up soon.
