EzyDog's Cujo Shock Absorbing Leash is made with 6" of shock absorbing stretch to give you comfort and control when walking your dog. The 25" leash is specifically designed with a tighter, shorter stretch that allows for greater control over medium to large dogs that pull hard.
The Cujo 40" leash is built with 12 inches of shock absorbing stretch, and is suited more for small, medium or large dogs that do not pull when on a leash. The slightly less tight, longer stretch of the 40" leash is a great, comfortable option for both you and your well-trained dog. Both the 25" and 40" leashes can have standard extensions added on for additional length, or have the ability to add 2 extensions for dual tangle-free dog walking.
