%% Good point no nonsense; a martingale dog collar always works also, was designed for sighthounds [ greyhounds, not gambling, even though many gamble on grayhounds LOL] My banker dad made his own.............................................................................
Google is your friend. I actually thought that was some kind of option strategy... "Designed to prevent a dog from ‘backing out’ of its collar, the Martingale has a limited slip choker action. Also has become the training collar of choice among many dog trainers as it remains quiet when correcting the dog rather than creating a metal shank sound of a choke chain. Note: This collar should not be left on an unattended or unleashed dog."
%% Pekalow types faster than me LOL. I think it [martindale dog collar]was designed by a gambler or trader but i cant prove that LOL.WHY?? ; it gives the beast little more slack, but does not choke the life out of profit , i mean beast , like choker collar does
