No, most horses don't need standing bandages. Even though a horse's legs may become slightly inflamed after a very strenuous workout, inflammation (as long as it doesn't cause lameness or happen too often) is actually a part of the horse's body's natural healing process. Unless your horse is in training, competition, or your vet has recommended standing bandages, standing bandages probably aren't something that you need to make part of your routine horse care practices.
