Do you massage your horse regularly or do you occasionally have a masseur treat your horses? Then you know that it is hard work to reach the deep-lying muscles properly.
A masseur or therapist can never be replaced. We also recommend that you regularly have your horses checked by a therapist, but you can massage your horses in between yourself.
There are many massage devices and blankets on the market that would make this easier. But light equipment or a blanket with moving elements can never completely get through the deep muscle layers of the horse.
