There are many reasons you might want to walk your horse out instead of riding out. Your horse may need fittening up or he may be unrideable but okay to walk out so it could be great exercise physically and fun mentally for him. You may be working on getting a better relationship with your horse so walking out would really help you bond OR you may just enjoy walking your horse out.
Sometimes, when a horse is sceptical or worried about being out hacking it can help to walk out in-hand regularly to familiarise to different surroundings, sounds, sights and smells. Once you get used to things you can always decide to mount and ride a bit and if you are riding you can always decide to jump off and walk a bit too.
For Solly and me, walking out in-hand is really helping us to bond in an unfamiliar environment, it helps us look at things together face-to-face where I can read him better. I also have two ageing dogs and this helps give me my much needed exercise. I really enjoy walking out and it’s great to have my good friend Solly out with me.
