Rescue dog any guess on breed?

Rh
Hey guys got my little but chunky rescue today he's 18 months old and a pure darling to have around already! As you can see he's a big bones boy and my gosh so so gentle! Kennels had him down as a bull terrier cross but we are unsure of what bull terrier and what cross he may be? Any ideas? Would be great 🐾🐶
