After Wauzi has grown out of the old Norwegian Harness, was due a new one. Advantages of this harness: When Wauzi pulls on the leash, he is not choked (the old Norwegians was the case) - the chest strap is deeper; Dishes must not be pulled over the head for turning on and Ausziehen- my dog did not like that; the shutters are relatively easy to open, as opposed to the click fasteners you need but at least it look when opening and closing and they are variable, so there is no permanent employment, they are adjusted each time a new beginning; the material is at the points that touch the dog soft and it is easy;
