Review on TAIDA 20ft 30ft 40ft 50ft Nylon Long Training Dog Leash for Small Medium Large Dogs - Obedience Recall, Camping & Backyard, 1 inch Wide by Sean Davis

I ordered this on the recommendation of a trainer (yes, this one). Judging by their video, don't make too much of a difference when your pup is carrying it in their mouth. For use in the garden so you can gently tug when they get naughty. The line was in my 6 month old pup's mouth less than 20 seconds and her needle teeth went right through that thin line rendering it useless to me, broke off completely and my little one could have freed herself. I have invested in a leash, very strong and thick, like a real leash.
