Welcome to PondBoss,Where in Ohio are you located and perhaps I can steer you to someone local in the know concerning your windmill and pond problems. As far as your dog getting sick how does this relate to your pond?Is this something A Vet has diagnosed?You are off to a great pond management start just by finding this site, search its contents for many Pond Management 101 discussions. I would also get the books that Bob Lusk has written (available on this site) about pond management and for sure subscribe to the PondBoss magazine.
