Using this dog leash is easy. Just attach the safety 'Snap - In' Hook to your dog's collar. You can carry dog waste bags in the dispenser for a clean walk. When walking, hold the leash firmly to have good control. Make sure to choose the right size according to your dog's weight. For size M, it's for dogs up to 25 kg, and size L is for dogs up to 40 kg. After each use, check the leash for any signs of wear and tear, especially the hook and the rope. If there are any damages, replace it immediately. To keep it clean, you can wash the nylon rope with mild soap and water, then let it dry thoroughly. Avoid exposing the leash to sharp objects that could cut the rope.
