Jacob and Jackson LOVE each other! They really are such good friends! Jacob can now open Jackson's crate and let him out when we have guests over....that's FUN! :) He can also lay on top of him and easily roll off with a big laugh! When Jackson needs to go outside, just send Jacob to the door and he'll open it for him, deadbolt and all. If Jacob starts to cry during a nap, Jackson heads right to his door and sometimes goes right in. We've got our hands full with these two, but we wouldn't have it any other way!
