Thanks for the regal comment!
When Jazz was 6 or 7 months old, I was playing with him along the beautiful, Nishiki River, about 15 minutes away from our home, by car. Just your typical frisbee, ball, stick outing, until Jazz locked-in on a giant bird (grey heron) about 50 yards downriver. It was perched right on the edge of the river, of course. Jazz must have thought it was one of the pigeons from the park near our home, only bigger. I figured he'd never catch it, so I commanded, "get the pigeon!". He crept and froze, crept and froze, and then, took off like lightning after the poor, stunned bird which (thankfully) caught sight of Jazz coming, and flew away just above the level of the river, and along the river. Jazz kept following hard after it, so the wise bird turned to fly across the river, but at the same, low, just-above-the-water altitude. Jazz followed right after him until the 2-or 3-inches of river turned into 10 feet of river. Jazz vanished completely below the surface, and within a second or two, was up, spewing river water from his nose, grasping at air with his front paws, having had his first swimming lesson. Oh, I had yelled for him to stop, but he must have determined if the "giant pigeon" could run across the water, so could he! My younger son, who was right behind Jazz, pulled him to shore, and then we both about died laughing at our soaked dog. We made sure Jazz learned how to swim shortly after that episode!
Now, whenever he sees a heron, I have to really make sure he stays put, because he will really go after it with a passion.
