I've been trying to get a video from my friend of me crossing otter creek, water just below my butt rushing crazy after a night of thunder storms carrying my 60lb dutch sheperd on my shoulder. There was no way he would be able to cross safely and he was too scared to try it anyway. i have had to do this a few times unfortunately, not really the safest thing to do, pretty intense actually and its usually just us two on the hike. I use keen slip on sandals when crossing even in winter, I keep them strapped to my pack and use them as camp shoes as well. I think the next K9 will be a dutch retreiver haha
