Dogs on Sailboats
We have 3 labs, not all of whom would be on the boat at any one time. However we have had two at a time on the boat and always have them on a harness with a strong leash to keep them close. Years earlier, we used to let our black lab roam the deck since she seemed so sure footed, and we had nylon cord lacings between the life lines and the toe rail, However one spring day, she slipped and went backwards right thru the lifelines and lacings. We were able to retrieve her and get her back aboard by way of carying her up the swim ladder, but we never again sailed without either a harness and/or life jacket and have fortunately never had another incident.
