Abstract

A leash for walking and controlling an animal, such as a dog, is provided with redundant connections in a single leash. The leash includes a quick-release clip for connecting to the fixed collar on the animal and a slip collar. The slip collar is normally slack, unless the animal escapes the quick-release clip or collar or harness. The slip collar is arranged to slide into a ‘choke collar’ configuration during this attempted escape. This single leash advantageously provides for redundancy.
