I'd say Josie would for sure. I've been walking at night and some drunks have come up to me and creeped me out, and Josie flipped out when he got too close and scared him off. I think she would protect me. We've done the "mock fighht" think and josie jumps up like she doesn't like it

I duno about Zeke..I've never needed protection to say so or not.
