A dual-action collar for walking or training. The only design for greyhounds and similar dogs that back out of regular collars. Martingale-syle with an additional sewn in D-ring so it can be used either as a limited-slip choker or as a regular flat collar.
Don't forget your matching leash and harness.
Note: For walking and training only. This collar should not be left on an unattended or unleashed dog.
