A leash is a flexible strap or cord used to control and restrain an animal, typically a dog. It is attached to a collar or harness, allowing the owner to guide the pet during walks or outings. Leashes come in various materials, lengths, and styles, catering to different needs and preferences. Using a leash is important for safety, as it helps prevent pets from running away or getting into dangerous situations. It also promotes responsible pet ownership by ensuring that animals are kept under control in public spaces, protecting both the pet and other people or animals in the vicinity.
