30+ years ago, my Newton dog walker friend went in to the pond by the DeCordova Museum in Lincoln after her golden retriever that had fallen through the ice, and my friend drown.
25+ years ago my golden retriever, Charlotte, went into the Charles on our weekend run one March morning, off the really beautiful trail that goes along the river behind the police firing range, just at the point where the river turns, such that the full current hits the bank where Charlotte went in. Because all the flow hitting at that point, the current was so strong that Charlotte had trouble getting back to the opening, despite paddling as fast as she could. For a few moments as I watched her struggle, I contemplated going in to help her out. Why not, after all, I had gone in the water to “teach her” to swim as a puppy – but that had been summer. Fortunately, Charlotte put on one sustained strong effort and got back to the opening and climbed out, and only one of us went home icy wet, while the other was left with strong memories of what almost happened.
Charlotte always went in the water on our winter runs, unless things were frozen solid.
