Wide martingale collars are lined with micro suede and have a D-ring to attach to a clip-on leash. Collars measure 2” (50mm) wide in the center of the neckpiece and taper to 1” (25mm) wide on the sides; for mini dogs select the 1-1/2" (38mm) wide collar. A sliding plastic 'stopper" makes it quick and easy to tighten the collar after sliding over your dog’s head or to remove the collar. This collar style prevents your dog from escaping by tightening up if the dog tries to back out. Scroll down for collar measuring instructions. NOTE: A properly fitted martingale collar should be comfortably loose when there is no tension on the leash. When a dog pulls, the martingale collar will tighten to the dog's actual neck with buckles either touching or slightly apart.
Measuring your Dog's Neck: To choose a collar size, measure around the thickest part of your dog’s neck behind the ears - a fabric tape measure or a string works best - or measure your dog's current collar from end to end (closed).
