Herm Sprenger Black Stainless Steel Chain Training Collar.  Please measure your dog's neck, and the widest part of their head to ensure proper fit. If your dog is in between sizes please go up a size!  Check collar fit when using on growing dogs to maintain proper fit.  Please consult a training professional with any questions.  

We recommend adding 4" to the neck measurement for collar fit if you cannot measure the widest part of your dog's head.
