my dog cornered some sort of snake just now

I think it was a bull snake. It looked a lot like this

my neighbor has cleaned out an over grown fence row and prolly forced it out of it home by his activity. It was crossing my yard to another fence row when my dog found it. She was as scared of it as it has of her. I after letting her prance around barking at it for a few minutes, I picked it up with my rake and took to it to the woods
