Thanks everyone!
Yup, I do have a quick release on my jorring setup. Never had to use it and I do release for descents and use alternative stuff like flexis for where shortroping wouldn't work.
Thanks for your concern, Jay! Wouldn't attempt this with an untrained dog, that's for sure (or anyother form of tethering!). Dog training has become an obsession and the jorring stuff is the result of lots of hardwork in obedience, agility, and herding lessons; it's just one more way for me to celebrate the joy of teamwork and cooperation with my little canine buddy.
I'm hoping to find a trainer who works with sled dogs here in NY; all this jorring stuff springs from dryland training for areas of the country that don't experience year round snow cover. If anyone knows of such a trainer, please PM me with thier contact info.
I've seen the springers and actually I've gotten lots of replies on those on Traildogs forum (yahoo). They do look very cool!
Actually, all of the biking I do is here at home on 60acres of hayfields and wooded pathways but lately we've had issues with coyotes trying to bait the dogs out and I'm a little concerned about that, so anything I can do to keep my little buddy safe, I'm all for.
Thanks to everyone who responded, your tips and advice, as always, are much appreciated.
