This dog loves to run around in the marshland. What I mean with running is the kind where he goes as fast as he can and pieces of wet marsh fly around. It is apparently also fun to the crab pieces of it with your mouth and throw them in the air. No running for me as I will just sink in and get stuck. It is however a popular training method with some athleths like cross country skiers, to run on marshland. Then there is swamp soccer. They hold Swamp Soccer World Championships in Finland every year. I hear it’s tough and messy but also a lot of fun.
