Many dog owners struggle with leash-related problems, including leash pulling, reactivity on a leash, and even leash aggression. In this short video, I explain the benefits of using a long line for handling and training dogs. Instead of the conventional 4-6-foot walking leash, I recommend using a long, 10-15-foot training line. This long leash can be made of leather, biothane (also known as vegan leather), ribbed biothane, or cord. Unlike fabric or nylon, these materials are heavier and less likely to tangle. Working on a long line eases tension on the line, gives the dog a degree of choice, helps us forget that there’s a line connecting us, and makes walking together a habit that’s developed gently over time.
