That is why we bought our 34' georgie boy mh, we have a large 10 yr old golden retriever. We would never board her, it would break her heart! Only problem now is that her back legs are very weak, so shes afraid of the 4 steps to get in. This last trip we had to put a large bath towel under her belly and lift her all the way up the steps. We camped at the Jacques Cartier ny state park on the beautiful Saint Lawrence river a few weeks ago and she took a few swims in the river, I think it felt good on her achy old bones! :-)
