Encounter with a Swan

Dylan has a tendency to chase any creature that will run from him (though as far as other dogs are concerned, he much prefers to be chased). On visits to the lakes, he sometimes has to be restrained to prevent him from chasing the Canada geese that congregate in large numbers. Recently, he saw something moving amongst the reeds that grow along the stream that meanders between the lakes. Without warning he leapt after what was probably a moorhen. He is no longer frightened of water, but generally prefers to paddle and has rarely swum. It was a shock, I suspect to both of us, when he plunged into the middle of the stream to be momentarily completely submerged. My only concern was that he would have difficulty scrambling up the far bank, but he managed this to emerge a cold and bedraggled dog.
Yesterday, having almost completed a circuit of some of the lakes, he sped off just out of sight. I went to investigate to discover him circling a large, though still immature swan. This bird, unusually, was on dry land and, it was not amused. With outstretched wings and furious hissing, it was keeping Dylan at a safe distance. The dog, for his part, considered it great fun and I doubt very much that he realised the true extent of the danger. Fortunately, the lure of the offer of a biscuit was enough to draw him to a safety.
