Chester, the dog, speaks German!!

I took this little video as the little twins were riding our horse down to the bus stop to meet their 1st grade brother, Jonathan, when he got off the bus. I have to apologize for the noise (horse hooves on gravel is loud) and for the terrible bounciness of the video (I was walking backwards while leading the horse and holding the camera in my left hand). Anyways, the reason for posting this video (besides it being so cute), is that I thought it was funny how up to this point, the kids had been addressing the dog, Chester, in English. All the big people addressed Chester in English, so it was just natural that they also addressed him in English. I'm sure they just figured that the dog only knew English. Anyways, as we're riding along, Simon keeps calling to the dog (who never obeys anyone--ever) in English, and of course, the dog was not coming. So, I told Simon that Chester only spoke German. And, just my luck, the minute Simon calls out to him in German, Chester pops out of the bushes. The kids are delighted with the new discovery that their dog speaks German. And the rest of the ride, they continue to call out to him in German. Since then (and this was about a week ago), I have noticed them addressing Chester in German much more frequently.
