dog leashes (also known as dog leads). 

They are used to guide, lead, and control a dog during walks, ensuring safety and security. 

The leashes in the image are made from a braided rope material with a hand loop on one end and a metal clip (carabiner) for attachment to a collar or harness on the other. 

Different lengths and materials are available for various uses, from short leashes for urban areas to longer ones for more freedom in open spaces. 

The leashes come in various colors, including blue and black, red and blue, and olive green.
