Training a lizard to wear a harness requires patience and a gradual approach. Start by introducing the harness indoors in a calm environment. Let your lizard wear it for short periods while supervised. Reward them with treats and positive reinforcement to create a positive association. Allow your pet to move around with the harness so they get used to the sensation. Over time, extend the duration of wear and monitor their comfort. Always prioritize your lizard's well-being and never force the harness on them. With patience and gentle training, many lizards can become comfortable wearing a harness, enabling safe and enjoyable outdoor experiences.
