I've been trying to come up with a design for JD. So far, we do have a screened in porch on the shed that he can run free in, but it can't be accessed from the house--I either have to carry him out there, or put on his harness and lead. Would love to make a covered, elevated walkway leading from the back of the house out to the porch!
However, considering my limited carpentry experience, that's probably not going to happen.
