What breed is my dog?

I know she is a cross, and I got told, border collie/staffie. but she hasn't got any features of a staffie. In her personality she is a bit of a nutcase. Runs around the house like mad. pounces on every one. she isn't very spacialy aware. She will use people as trampolines when she is hyper. though on that thought, she's only 7 months old, and we are getting help for her. She is very sweet though. She is medium size. Sorry about the coat if you think it's strange, it's the only one we have of her standing still.

Just wondering what breed she might be crossed between?
