Besides my two King Charles we have good old Jack. He's a rescue dog from Mexico who is something else. He rides in our sand rail when we go to the dunes, and yes he's seatbelted in! Whenever we stop on a run, he jumps out, digs a hole under the rail and takes a nap until it's time to ride again. He loves it! We even have people come up saying, "oh, it's Jack we've heard about him!" LOL!
