Couldnt address the treadmill, I run with my dogs. spring poles are great for training commands and excercise; between 2am and 7am are the best time generally, although right about dusk into an hour after dark is a good time too. Yeah I've run across dens and even a freshly killed porcupine being eating belly first on one occassion (wolves are the only predator that can succesfully kill porcupines in N.America.) With the dogs as drones they are seeking for game to catch and me shortly behind predators are clear on who is being hunted.
Start small with the ones that cross your path and your yard. Go hunting after your dog is seasoned from protecting the land and looking out on walks and treks.
