Leash walking
What is a long line and when should I use one?
Last updated 23 September 2026 · How we write and check this
Short answer
A long line is a lightweight leash typically 5 to 15 metres long, used in open, low traffic areas to give a dog freedom to sniff, explore, and practice recall while still attached to you. It is not suitable for busy streets or crowded parks, since the extra length is difficult to manage quickly around people, cars, or other dogs.
What makes it different from a leash
Unlike a standard leash, a long line is designed to trail loosely on the ground much of the time, only being gathered in or paid out as needed, similar in spirit to how a fishing line is managed. Biothane or treated nylon versions resist tangling and mud better than plain cotton webbing.
Good situations to use one
An empty field, a quiet beach outside busy hours, or a large fenced park with no other dogs nearby are all good settings, giving a dog 10 metres or more to sniff, run, and practice coming back to you when called, all while remaining safely attached.
Handling it safely
Never wrap a long line around your hand or body, since a sudden run from your dog can cause a serious rope burn or even pull you off balance. Wearing light gloves and letting the line run loosely through an open hand gives more control with less injury risk.
Key takeaways
- A long line is typically 5 to 15 metres, used for sniffing and recall practice in open spaces.
- It is not suitable for busy streets, crowds, or areas with other off leash dogs.
- Biothane or treated nylon resists tangling and mud better than plain cotton lines.
- Never wrap a long line around your hand, since a sudden pull can cause rope burn or a fall.
