BarkBot Heavy Duty Martingale Dog Collar, Blue XL with Reflective Tubes and Quick-Release Buckle

BarkBot’s Heavy Duty Martingale Dog Collar is a blue XL collar designed to help handlers manage pulling, with a two-in-one tactical and slip martingale design.

• Double-layer heavy-duty nylon webbing — forms the collar for everyday handling in different scenarios.
• Thickened SBR inner layer — provides a soft, breathable surface against your dog.
• Two reflective tubes — help make your dog more visible during nighttime runs.
• Thick zinc alloy buckle, tested to hold up to 400 lb (181 kg) of pulling force — offers a secure fastening with easy on-and-off use.

This collar is made for handlers who want a way to manage pulling during walks and other activities. Its martingale construction tightens gently when a dog pulls, while reflective details are intended for nighttime visibility. The fit guidance helps you choose a size based on your dog’s neck measurement.

How does the martingale design help with pulling?

The collar combines tactical and slip martingale styles, tightening gently when your dog pulls to support handler control. Its double-layer nylon webbing forms the collar body, and the design is intended for use in different scenarios. It is made to help manage pulling; the provided features do not promise to stop pulling altogether.

• The two-in-one design brings tactical and slip martingale features together.
• Heavy-duty nylon webbing is layered rather than single-layer.

What materials and visibility details does the collar have?

The inner layer is thickened SBR submersible material, designed to keep the inside soft and breathable against your dog. Two reflective tubes add a visibility feature for nighttime running and can make your dog easier to see in low light.

• The SBR material is used on the inside of the collar.
• The reflective elements are tubes, with two incorporated into the design.

How should I measure for the XL collar?

Measure your dog’s neck and leave about one finger of space between the measuring tape and the neck. If the measurement falls between two sizes, choose the smaller size for the recommended fit. The product is identified as XL, but no neck-measurement range is provided here, so use the stated measuring guidance when assessing fit.

• Allow about one finger of space while measuring.
• For a measurement between sizes, select the smaller size.

BarkBot’s blue XL martingale collar suits handlers looking for pull-management features, nighttime reflectivity and an easy-to-fasten buckle. It is intended for use with a dog whose neck measurement suits the selected size and for situations where gentle tightening is useful. Its defining combination is a tactical and slip martingale design with a reflective, double-layer construction.
