Like Pat said, if you haven't split it yet, do it yesterday. Whole rounds will split somewhere as the outside dries. By splitting them now you can keep it from random checking-dogwood is really bad to check anyway. I would also debark them yeasterday, and seal the back of the staves. I've had a lot of good wood ruined by bugs over the years because I didn't get the bark off soon enough. The drawknife works great, just be sure to keep the beveled side down so that it doesn't dig into the wood and violate that first ring.
