The powerful iconography of individualism is depicted in geometric lines showing a jagged mountain skyline, and the first dogƒ??the wolfƒ??howling for all to hear. Hear it?!! WHAT IS THE REACT LEASH ? ?ÿSometimes on our daily dog walks we get into situations that require a little more control than is offered by a standard leash. At a crosswalk in the city. When a varmint flees in front of your ever-vigilant canine companion on a trail hike. Maybe itƒ??s youƒ??maybe youƒ??re just a control freak . ?ÿ With its dual-handle design, the React Leash makes taking control easy with an extra handle very close to the leashƒ??s collar attachment, bringing maximum control as close as possible to your beloved and sometimes boisterous beast.
