Beware of dog!!

went riding today on the gravel north of town, (the route we took last time). I had company for a little while, a big white Boxer/pit bull looking dog chased me for a quarter mile each way. This was the dog we saw last time that came part way across the field towards us. He didnt try to bite me or anything, just barked loudly while making a general nusence of himself. I swear he was saying "hurry up fatty" at one point. Also, it looks like they put down fresh gravel in several spots so it is a little deep in a couple spots. I didnt have trouble, but just wanted to warn u guys riding skinny tires.
