An important aspect of dog leashes is their sturdiness. Although rope leashes are quite cheap, they are vulnerable to chewing and fraying and are not amongst the most recommended types of leashes. However, it is considered that a better type of leash is the one made of nylon because this material provides a bit of elasticity which is meant to result in more comfort for the dog. On the other hand, nylon leashes can cause chafe or can cut into the skin of the dog.
Leashes are used on large animals—such as bovids, camelids, and equids—to lead them so that they will be forced to follow and come to a desired area—as well as to tether them to a specific area, such as to a fencepost or tree trunk, so that they will remain stationary and not run away. Oftentimes, leashes are used to tether such animals when they require separation, examination, or work to be done to them, such as grooming and tacking up.
