can anyone help me identify my dogs breed?

hi im new to this site and im asking anyone who might know the answer to me question for some help,i recently bought what i believe was a rott x mastiff bitch,i had my doubts after a while that this was indeed her correct breed due to her size,iv since been to a vet and in her opinion my dog (amber) is most likely a staffy x mastiff,but she cannot be sure,can anyone help me to identify her???thanks....pic can be seen below

the pic is up

awe so cute, she looks like a wee bullmastiff

what age is she? what sort of size is she

i will post another picture of her standing,we were told she was 5 months when we got her so it would make her around 9-10 mnths old right now,if the info we was given is correct

Staff mix would be my guess.
