Police devices don ' t , but with all of the surplus equipment floating around , I ' m sure someone could make it happen . <| sep |> I had a job for a few summers where I got to teach a trail obstacles class and accustom horses to new things like water , walking across a tippy bridge , walking across a tarp , stepping over poles , and walking with the dreaded emptymilkjugfullofpebbles dragged along behind on a string . If I ever got the chance to do it again I ' d take it in a heartbeat . One of the most hilarious and entertaining experiences of my life and way better than teaching Western Equitation . I had a large supply of carrots and often would have to physically place their foot onto something or give them a clap on the hindquarters to send them across . Watching their riders usually rich city girls cling to the horse in terror as it stared wide eyed at the offending obstacle and pranced around it or stood over it with legs splayed out as far as possible in every direction was just icing . In the end though , after a week of terror for horse and rider , we ' d have all but the most stubborn ones navigating each obstacle , and it was good knowing that both would be that much safer if it was actually encountered on a trail ride . Good times , many laughs to be had . Horses will often kick at something that scares them , and this photo is actually a pretty typical tantrum . They ' ll do the same thing on a tarp until they get it into their heads that it ' s not hurting them . EDIT Some people below have questioned whether this horse is afraid of the water . It ' s certainly nervous , but after it ' s entered the water it ' s not panicked , or it would be out of the water in short order . I don ' t agree that it ' s playing or having fun though . You can see its ears cock back in the classic I don ' t like this position but then forward to the what is that position between bouts of kicks . Seems to me that the horse trusts its rider enough to follow her into the water but still isn ' t sure what it is and is kicking at the strange thing that has just suddenly made its legs wet and cold .
