Green Way Outdoors is dog-friendly. They rent boats in Pennsylvania. It's up to the owner if they want to bring their pets along with them to enjoy a boat ride. Dogs and humans are not allowed in the lake itself, as it's used as a water supply. They also have a dog-friendly trail on dry land too. Dogs need to be leashed and registered before entering the park. You can contact them 24/7 to try their book a rental on the water.
