The Flexi Classic Tape Medium/Large has a 5 Metre tape and is suitable for dogs up to approximately 50kg. The Flexi retractable dog leads have become one of the most popular ranges of dog leads in the world. Flexi leads never slacken, as the lead is always subject to sufficient tension and as the animal walks closer, the lead retracts into the handle. With the help of the integrated braking system, the dog is always under control and the length can be adjusted and locked in place if required with the locking button.
