ThunderSnap is a brand of ThunderWorks, the makers of ThunderShirt, who have a mission to find simple, effective solutions for the most common problems faced by pet owners and their loved ones. They are dedicated to helping pets relieve anxieties, over-excitement, pulling, jumping, barking, and much more. ThunderSnap was designed to help putting on a leash as quick and convenient of a process as possible. ThunderSnap uses powerful magnets and a strong ball-bearing latch mechanism to easily and securely connect to any standard dog collar. The collar cap attaches to any D-ring with a simple but strong metal clip that can be left indefinitely for convenience, and the leash “ThunderSnaps” to the cap when you’re ready for a walk. Tested on over 300 pounds of force, this leash is sure to hold even the strongest puller.
