A wonderful dual-action collar for walking or training and the only design for greyhounds and similar dogs that back out of regular collars. Rated the Top Pick by a national canine publication. Martingale-style with an additional sewn-in D-ring so it can be used either as a limited-slip choker or as a regular flat collar.

Available in size ranges:  10"-14", 14"-20" and 19"-27".

Note: This collar should not be left on an unattended or unleashed dog.
