A wonderful dual-action collar for walking or training and the only design for greyhounds and similar dogs that back out of regular collars. 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: 15"-22" and 19"-27".
Not recommend to be left on an unattended dog.
Lifetime guarantee - even if chewed!
