Help your dog look the part when you take him to the crags for the day with the Ruffwear Knot-A-Just Dog Collar. This adjustable collar is made from durable 10mm rope and works great with dogs that have thick, bushy hair. The low-profile design settles comfortably in the dogAAAs hair without snagging. Reflective trim helps him stay visible around town, and a stainless steel O-ring and a separate split ring keep his leash attachment and ID tags separate.
