The belt ideas are great, so is that harness idea from SouthernGirl!! I put Buddy's ordinary cloth leash on a belt i borrowed from my guy, and WA-LA, instant belt-leash. Men belts are very strong and can fit over your coat, too, so borrow one from Dad. One more idea, for painful hands, is, get an extenda leash with a very comfortable grip, some are rubbery padded a bit, nice feel to them. BUT, and listen to me real careful here, do NOT let Seamus know it extends, for real, just don't do it. NOt while he is in training, not even once. I made this mistake, i learned that the hard way. Later on, after Seamus is "Mr. NeverPulls" the king of loose leash walking, then you can let him know about "this leash gets longer if you pull". LIke maybe this winter, lol!! so til Seamus has learned loose leash walking, if you get an extenda leash with comfortable grip, measure out how many feet you want (not many) and LOCK IT THERE, AND TIE A LITTLE KNOT in the leash right there, so it is consistent for Seamus to get the hang of "how long the leash IS". again, you have to get everyone on board for this, no one can ever unlock it and let Seamus find out "if you pull, this leash gets longer" while he is in training.
