Resistant material: The dog strap is made of high quality nylon and is ideal for walking with your dog without worries. It is also suitable for all small, medium and large puppies. The carabiner is made of metal, so it is robust and resistant. Excellent design: the rope with this length helps you easily control your dogs near or far, which reduces low back tension and the risk of muscle injury. This design helps mitigate rapid movement when using energetic and active dogs. Multicolor and length: We provide multiple colors: black, yellow, blue and orange. And we also have several optional lengths. You can choose the color you like and the length you need.
