Even if your rabbit runs around in your house, it is better to take them out for a walk on a leash and give them proper training. Here is a step-by-step tutorial to do so: 1. Find them a proper fit harness (an H-style harness is best). 2. Let them choose whether to put the harness on or not. If not, try several attempts. Give them assurance that it is safe! 3. Let them be comfortable with that thing wrapped around their belly. 4. Start small walking sessions inside first. 5. Find a suitable and familiar spot outside for the walks, and take them regularly or alternately, so that they can adjust to the new place. 6. Let them do the big task, which is long walking. 7. Make sure they are safe outside. Don’t leave them alone. Keep them as far away from predators as possible, even big pets or stray dogs. 8. Check to prevent heatstroke.
