My son Collin was practicing paddling in the canoe. The canoe was tied to the dock and we'd push it out so he could paddle inot again. Buddy (the dog) saw what was happening and thought Collin was in trouble. He grabbed the rope with his mouth and pulled the canoe to the dock. My son was not in any real danger but we were amazed at how quickly Buddy "rescued him". My son thought this was the greatest and wanted to do it again and again!
