The Flexi New Classic Dog Leash S is the perfect leash for dogs with a weight up to 12 kg. This cord leash has an improved braking system. This allows you to halt the roll-out system in 1 move. Move your finger over the slider of the braking system, than the leash remains on the desired length. The leash gives controlled freedom of movement to your dog, because you can determine yourself how many meters you give to your dog.
