http://ift.tt/2mR3WDk I take care of my mom's 3 large dogs. One of which is a 100 lbs mixed with husky, and all can use the extra excerise. I was going to get a puprunner back in June, but when was going to buy it they ceased production due the cretrator unfortunately passing. Although I would just wait they haven't made any since and this thing is perfect for me and for where I live. But I don't know much about how to build stuff like this but I have family that does and I can be resourceful. Thanks via /r/DIY http://ift.tt/2mpfLEY
