Yes, you can train a pet rabbit to walk on a leash. It is important to use a specially designed rabbit harness and leash to ensure the rabbit's comfort and safety. Start by getting your rabbit used to wearing the harness indoors before attempting to take them outside on a leash. Gradually introduce the leash and harness in a safe and controlled environment to help your rabbit adjust to the new experience. Positive reinforcement, patience, and consistency are key factors in successfully leash training a pet rabbit.
