Wesley has started to blow us off (he is just over 2) and I no longer trust him to stay by us off leash... We take him hiking on the weekends and the last few times, he has taken off out of eye-sight. This would be fine with me, if his recall was excellent, but it is not great in high distraction, so, we are going back to the beginning and I am thinking that for hiking and outdoor activities, rather than a leash, he should be attached to some sort of drag line so that he doesn't feel like he is wearing a leash (which changes his behavior), but, I can enforce a "here" command (we are replacing "come" which is useless from overuse by DH).
My question is (and I apologize for the long-windedness, I just wanted you to know what I want the line for), what do I buy and where do I buy it? Is it just a rope? What is it made from, how long should it be, and how should I attatch it to him (tie it to his collar)?
