Could he be crossed and if so with what

Hi my partners been concerned about what our staffy could be crossed with as he's a very big boy,

He has a 36 inch chest 21 inch head a round
33 inches from  nose to start of tail
Stands 21 inches high to his back

Just generally a beast

He is a large fella that's for sure and definitely more Staffy than anything else. I'm rubbish at calling out what the crosses are but he just looks like a very heavy set Staffy to me

He looks a like a staffie to me too. Without wanting to sound too rude, some of his measurements could be down to him carrying a few extra pounds.

I know he's carrying a few extra pounds we tried get him loose some when we had him but he's just a big boy, when he stands in the window barking ya can see every muscle and he does go up like a triangle he's 6 and a half stone

In that last picture he doesn't look much taller than Roxy though obviously more heavy set

Roxy is about same night as Tyler but she's crossed with a bullmastif so we know why she's so tall

if he's 6 & a half stone, then I would say he's definitely a cross. the bull terrier a few doors down from me is only 5 stone & BTs are a fair bit bigger than staffords.

He is a big boy but looks mainly staffie to me I'm always asked what Katy is crossed with, her parents were staffies but what was further down the line I don't know! She last weighed in at 4.3 stone, height 17", neck 18" chest 31", waist 26" but that was back in the winter, summer trim now
