The design of this collar is thoroughly thought. Firstly, it differs from the ordinary choke collars, as it tightens only to a certain limit in order to attract the dog's attention, so it helps to train the dog efficiently but avoiding a choking effect. Secondly, the dog will not be able to slip off his training tool, if properly adjusted. By the way, adjustability is one more benefit of the article.
To talk about its durability, it is great. The basic material is full grain leather, selected of the best sorts. It is flexible and tear-proof, thus, your martingale collar will serve your German Shepherd a lifetime. The martingale chain is brass - non-corrosive and super strong metal, that confirms a long-lasting service of the tool. Besides, the combination of dark-colored leather and shiny goldish brass looks stylish and attractive.
