Personally, my dog is a husky, and he had to fight his nature little to counter traction. With training sessions (with collar), the result was already satisfactory. With the harness, satisfaction is total, my dog absolutely pulls more, or else the occasional pull is much more easily manageable and more suffocating my adorable husky :)
Only flat, a little bit of fang unfortunate in his youth began a part of the collar. The product, however, is solid because after several use, despite the weakness he has not cracked.
I recommend ++++
