With the record high temperatures we've had over the last few weeks, instead of thinking about late season Ice fishing, I'm seriously considering starting my guy's Swim by training early. Our Swim by pond is 62 degrees right now. Is this warm enough to not add unnecessary stress to the process? Keep in mind he is a Brown dog so he is a bit "tougher" your average lab. I'm in no real rush, so waiting isn't a problem, but I also want to take advantage of the time I do have now, and this great weather.
