No ID tags to come off...your large dog's name is on the collar! ID tags are a great way to ensure your pet gets back to you safe and sound, but ordinary dangling tags can fall off or catch and pose a safety hazard, while embroidered letters fade over time. This clever collar displays your pet's name or your phone number (up to 20 numbers/letters) right on it in rustproof, nickel-plated studs guaranteed to never come off. No worries he'll lose it. A sturdy buckle keeps it firmly in place. Handsome, heavy-duty nylon comes in a variety of colors. Choose neck size, each collar has room for 20 letters.
