Never worn collar. Size is 20"-26" The Confluence Collar is the go-to stink-proof waterproof collar for dogs that love exploring in wet environments. And since with great water comes great stinkability, the collar features a coated webbing that fends off the funk. Flip, slide, and lock the cam buckles for an easy-adjusting and, ultimately, an easy-wearing collar that's comfortable for everyday wear. Includes reflective screen printing, and packed full of Ruffwear’s signature collar features: separate ID tag attachment point on the new piton-inspired tag holder, a silicone tag silencer, and a strong leash attachment point for a confident connection on-leash.
