I don't have any experience with dogs on the trail, but I was contemplating the same thing while riding it last weekend. I was paying attention to the trail and how it would be for big dogs in a trailer. It seems like the GAP would be fine, but it would probably be a rough ride on C&O. As mentioned above, a small dog in a handlebar mounted basket would be OK. Also, towing a trailer would have made a real mess of things while navigating the crowds on the trail for the last 15 miles or so into DC (we did this part on a Sunday afternoon with nice weather, so it was like an amusement park out there).
