We bought this harness for our senior dog who will be once again spending the summer on our boat. He's 14 now so needs more support, and might need to be lifted via the boat boom occasionally. We were looking for a full harness that would perform both functions, and this harness looks like it should fit the bill. So far we've only fitted it to him and done some test lifts (he's a 70 pound German Shepard) and so far so good.
