Ruffwear Web Reaction Martingale Dog Collar, Basalt Gray, 17–20 in, Reflective and Adjustable

The Ruffwear Web Reaction Martingale Dog Collar is designed to help keep dogs secure on walks, with a micro-adjustable locking fit and an adjustable neck range of 17–20 in (43–51 cm).

• ITW Nexus Airloc buckle and Tubelok webbing — help resist collar slip-outs when a dog pulls or lunges.
• Reflective strips and stitching — add visibility in low-light conditions.
• 18% recycled Tubelok webbing with a soft construction — is designed to distribute pressure evenly for comfortable wear.
• Micro-adjustable sliding lock — lets you fine-tune the fit and helps keep it from loosening during activity.
• Separate ID attachment and integrated tag silencer — keep an ID tag attached while reducing jingling.

For walks with a dog that may pull, lunge, or move around actively, a collar needs to stay adjusted while remaining comfortable to wear. The Web Reaction combines a martingale design with a secure buckle and adjustable webbing. Reflective details are integrated for walks in dim light, while a dedicated ID attachment keeps identification separate from the main collar closure.
