Our BioThane O-Ring Adjustable Flat Collar offers durability and a practical design, featuring a brass, Nickel, or Steal O-ring placed opposite of the buckle and D-ring:
• Convenient Design: The O-ring rests at the back of your dog’s neck, providing an easy attachment point for leashes or safety straps.
• Strong and Reliable: Small and Medium sizes have one rivet on each side of the O-ring, while Large and Extra Large sizes feature two rivets for added strength.
• Custom Options: Available in 3/4” or 1” widths and over 15 colors. Choose a Single Color or upgrade to a bold Two-Tone design for $8 more.
• Simple to Clean: After outdoor adventures, just rinse in soapy water, wipe it clean, and towel dry for a fresh look.
