Classic Brass BioThane O Ring Collar

Our brand new collar design integrates a solid brass O Ring opposite the buckle and D Ring. Because the O ring sits towards the back of your dog's neck, the O Ring is ideal for clipping a Leash or a Safety Strap more easily. Available in single color or Two Tone designs. To order, select collar size, select your main color and, if desired, choose a second color under the "Make Mine Two Tone" option. Small collars have a single rivet on either side of the O Ring to allow room for adjustability, all other sizes have two rivets on either side of the O Ring. 

Please review the sizing chart carefully, and triple check your dog's neck measurement before ordering. Watch this video for how to size your dog for a collar. Your dog's neck measurement should fall in the middle of the sizing range of the collar you order. If you are in between sizes, need assistance with sizing, or need a custom size, please contact us and we'll be happy to help! 

While we strive to keep all colors and sizes in stock, it's possible that your color selection will be out of stock or backordered. If that is the case, we will email you as soon as possible to ask if you would like an alternate color, or if you would like to wait for a restock. A restock typically takes 7-10 days, but can take longer.

Brass is rust proof, but can develop a patina over time and with exposure to the elements. Make sure to rinse your collar and tag in fresh water after a trip to the beach. Wash your collar and tag with mild soap and water periodically, using a toothbrush or a sponge to clean around where the ID tag connects to the collar. If you would like to brighten your brass hardware, make a paste with lemon and baking soda, apply with a cloth, let sit for a few minutes, then rinse with warm water. 

Our products are guaranteed against defects in materials or workmanship. Because each item is handmade to order, returns are subject to a 15% restocking fee. For more details, see our Return + Exchange Policy. Please note that BioThane is not chew proof and your dog should never be left unattended wearing a leash or long line. Remember that you are responsible for the safety of your dog, no matter what type of equipment you use. For more information and care instructions, please see our FAQs.
