Let 'em know your dog is here! Our Backcountry Bell attaches to your dog's collar to make their presence known on adventures. The heavy-duty, velcro attachment strap encircles the collar and features two strands of reflective tape. The built-in silencer allows the bell to be ‘turned off’ by simply placing the magnetic tab over the bell to silence it. To un-silence the bell, pull the magnetic tab off the bell and reattach it to the corresponding magnet inside the attachment strap.  Product Details Features 2 strands of reflective tape Built-in magnetic silencer tab 1" wide nylon + velcro attachment strap 3.5" overall length 1.5" diameter bell Made of lightweight aluminum Weighs 1.5 oz Wipe clean as needed Backed by our lifetime warranty!
