Our chessy is just over a year and thank god that she is starting to be a good hunting dog because this dog has really tested our patience. This dog has more energy that any human can put up with. In out in out in out, eat, eat, in, out... At our marina, the dog can swim for an hour. If anyone is thinking about getting one of these dogs, PLEASE do your research and know that you will need a ton of patience and you will have to deal with the most dominant dog in the world.
