I cannot seem to find the thread about "how far is too far" and I wanted to review some of the answers people posed so I thought I'd start a new thread. I wanted the experienced members of the forum, Dennis if you have time, or Dr. Ed, to weigh in not only on running long marks with a young dog but yard work as well. It was mentioned a dog running 3 marks of 150, 250 and 350, or so, doing the math thats only 1500 yards. Thats only 8 sends to the back pile of the TT, not hard to do at all, especially in the cool part of the year. I have a dog that will be turning 6 months in February so we'll be beginning yard work while the ground is still frozen. So should a guy watch how much running a dog does in yardwork as well, and any more or the same as on frozen ground?
