Electrocution's Shocking Effects on Horses

From the annals of Hoofcare and Lameness Journal and the Hoof Blog, here are some memorable accounts of horses who have lost their lives or been injured or at least caught my attention by their ability to conduct electricity:

In 2004, Horse and Hound told us about a horse that really got a warmup before the cross-country phase at the Blenheim Petplan International Horse Trials in England. Special Agent Wal had his studs in when he perforated a power cable with one of them. It gave him such a shock that he was thrown to the ground. The veterinarians still cleared him to go and he jumped a clear round. Way to go! Is that what the Brits mean with those "Keep calm and carry on" signs?

In 1999, a seven-year-old Manhattan carriage horse named Jackie stepped on a steel Con Edison service box cover on East 59th Street. She reacted by kicking her driver in the head, then collapsed and died. A spokesman for Con Edison said that the use of salt in winter may have corroded wires underground and that humans wouldn't feel the electricity because they don't wear metal shoes. But poor Jackie felt it on a rainy day, in a big way.

In Ireland in 2005, the Dublin Horse Show champion Dimmer Light and a stablemate were electrocuted when a short circuit from a light switch in their stable yard electrified the ground and gates, according to a very sad news report in Horse and Hound that I have kept tucked away. I think the ironic match of the cause of the short circuit and the horse's name always intrigued me as much as the electrocution angle.

One of my favorite all-time horse safety articles is from Windy Meadow Farm in Maryland. Eventer Michael Hillman was challenged by his water trough. Little did he know that every time his horse tried to take a drink of water, he was getting a shock to his lips! Michael's article, Dear Diary, I Almost Electrocuted My Horse Today is a classic. So is everything he writes!

My friend Cyrstal Kimball, editor of The Equiery in Maryland, told me a story about a time when she was out hunting and the entire field came upon a hot spot. "It was a downed electric fence, still hot, that electrified the wet ground in the surrounding area, and when the field hit it at a dead run, horses were winging off in all directions..." (But it sounds like they lived to tell the tale.)

None of us can remember exactly where or when the show was, but a dressage show in the Northeast had a hot spot inside the arena. Every time the horses came to the spot in the ring, they reacted.

And then there was the one about the horse owner who was driving down the road and had his trailer struck by lighting, leading to an electrical fire in his horse trailer. So it seemed like a really smart idea to drive right into a carwash. The horse was electrocuted and died.

Horseshoes and thunderstorms don’t mix: This old photo shows what was once an unsettlingly common occurrence in America: multiple horse deaths due to electrocution in thunderstorms. This six-horse hitch of Percherons owned by the Christy Brothers Circus was struck by lightning on September 1, 1923. They were hitched up for the circus parade when lightning hit a transformer nearby. The wet mud surrounding each horse’s shoes provided a perfect field. In addition to this team, four horses pulling the calliope and eight horses pulling the lead circus wagon were killed. And a few people, too. Thanks to the Wisconsin Historical Society and Circus World Museum for the loan of this photo.

Speaking of lightning, that is probably the most common way that horses are electrocuted. I'm still struck by the imagery in this amazing story about a polo player's horse trailer and his ponies being struck in New Jersey in 2008. They all survived but I just can't forget the description of the ponies going down "like dominoes". For your own safety's sake, read the article, which has a lot of good information about lightning strikes.

A horse named Sadie survived being struck by lightning in 2001. Her owner looked out the window and saw a cloud of orange smoke where her horse should have been. She ran out and found the horse on the ground; the horse got to her feet after a while and staggered around. After a few weeks she was fine, except for lingering foot soreness. Her vet attributed her survival to the fact that she wasn't shod.

We all live in a tangle of wires, in an environment with increasingly severe weather and crazy service problems for our utilities. Our horses, even if they aren't shod, have plenty of metal on their tack, hang out by metal gates, live behind electric fence, and require heated waterers in their paddocks in winter and electric fans in their stalls in the summer. The possibilities for any of us to be zapped at any time, in any barn, are high.

Think about what you're touching, especially with your bare hands on a wet day, and keep an eye out for horses that might need help. And if a horse is acting completely out of character, there might be a good reason why.

Aluminum Shoes May Have Saved Two Horses' Lives as Two Steel-Shod Horses Die in Possible Electrocution at British Racecourse

Video by ITN.

The worlds of both sport and horses were rocked today when news came from England that four horses had become agitated for no obvious reason in the paddock before the first race at Newbury Racecourse in Berkshire. The horses began rearing and falling as the jockeys were mounting. Within minutes two horses had died while two others rose back to their feet.

The rest of the horses continued to the start and the race was run, but track officials canceled the remainder of the program for the day. Rumors began immediately that the horses had been electrocuted, and that a groom had felt a shock come through the horse's body, and a lead line showed burn marks.

According to the Racing Post, unconfirmed reports suggested that some of the runners who actually took part in the race appeared to have burn marks around their mouths when their tack was removed.

In an interview late on Saturday, Joint Managing Director of Newbury Racecourse Stephen Higgins commented on the shoes worn by the four horses affected in the incident. He said that the two horses that died were shod with steel shoes. The two horses that went down and got back up were shod with aluminum shoes. The two metals would conduct electricity differently if a shock was transmitted through the grass.

He also mentioned that because horses have four legs instead of two, they are much more sensitive to electricity in the ground, and that that would explain why humans might not have noticed the electricity. There were also rubber mats on the ground which the horses were stepping off onto the grass when the incident occurred.

Commenting on the incident, Professor Tim Morris, Director of Equine Science and Welfare for the British Horseracing Authority, confirmed that a full investigation is under way: “Following the tragic events at Newbury today, our sympathies go out to connections of the two horses that died, Fenix Two and Marching Song.

"We have launched a full investigation into the events before the first race. Whilst there are suspicions that an electrical fault was the cause and this is being looked into by the racecourse and relevant authorities, it is important that we investigate other possible causes.

"Both horses have been sent for post mortem examinations and samples from both horses, and from the other two horses involved in the incident, have been taken and will be analysed. We will also be testing a sample of the water supply and have secured and will review all of the CCTV footage from the racecourse stables and footage from the parade ring itself at the time.

"We have gathered evidence and statements at the racecourse from the connections involved with the incident, including trainers, jockeys, stable staff and owners, the racecourse and BHA veterinary officers, and the racecourse executive including the health and safety officer."

On its Facebook page, the racecourse posted this message to the public:

"The whole team here is totally devastated and our condolences are with everyone connected to the horses and those that saw this happen. The Electricity Board are carrying out investigations now and a further statement will be issued tomorrow."

The British Horseracing Authority quotes Jonjo O'Neill, trainer of Fenix Two, as saying: "Kid Cassidy was in front (leaving the paddock) and he took a turn. We thought he was bucking and kicking and he went down on his knees then he seemed to be OK. Mine reared up and we couldn't get him back, it was like he was stuck to the ground. It was the weirdest thing I've ever seen in my life."

Marching Song's part-owner Graham Thorner said: "I was very fond of him and he had great potential. To a layman with no evidence, you would say it was electrical. The lad who was with him was saying 'I'm getting an electric shock off this horse'. It can't be coincidence four horses have done the same thing and two have died, all in the same area."

Press assistance from the British Horseracing Board was instrumental in preparing this report.

Ice Capades: New Englanders Are Still in the Dark Tonight

APTOPIX Ice Storm "IDYLLIC", originally uploaded by nike6.

Throughout New England, more than 600,000 households are still without power following Friday's horrific ice storm that laminated the landscape, sent trees crashing into homes and barns, closed roads, blocked driveways, damaged vehicles, and sent the normally hardy residents of New England into candlelit darkness in their cold, cold homes.

Sure, lots of resourceful people have generators and the old-fashioned types of wood stoves and fireplaces that still burn real wood. But all those who own horses and livestock are experiencing the double challenges of meeting their own needs as well as those of horses who may not have on their winter shoes with ice calks. Horses that should be turned out, but the paddocks look like a hockey rink. And the fences are electric, anyway. Horses that need water, but the pumps are electric too. Horses that need hay or grain, but the driveway is blocked and the feed store is closed, without a doubt.

For many people, a horse is the only way to get around. Tree branches still lie on top of cars and trucks and block driveways.

December is a busy month for the farriers around here. The show- and sport-horse customers want a final set of shoes before the horses leave for Florida or Aiken or Southern Pines. And the grin-and-bear-it stay-at-homes want to delay putting on expensive winter shoes for as long as possible. They gamble for another week, another month, especially this year with so many people losing jobs or having just taken a heavy hit on the stock and real estate markets. They remember hacking out throughout the winter on bare ground last year, the year it forgot to snow.

So far, I have only been able to speak with one farrier. Phones are out everywhere, and cell phone chargers dangle uselessly from dead outlets. Not so for one farrier: Tom Maker has 50 Morgan horses to take care of at the beautiful old Townshend Farm atop a hill in Bolton, Massachusetts. The town, which is about 30 miles west of Boston, has been shut down since 10:55 p.m. on Thursday night, the exact moment the power died. Law enforcement has all roads closed in the town: no one goes in, no one goes out.

Tom said that, even today, if you stared at a tree line in any direction for a minute or two, you'd see a treetop break off. He said that virtually all the trees had been topped off, as if a helicopter flew over and trimmed them. Falling limbs buried the fence lines...and became fences themselves.

Unfortunately, Tom said, his clever Morgans are learning that the juice to the fences is off. He has one generator to use at two houses, an apartment, and a big barn, in an attempt to keep all the water pipes and drains from freezing.

Another handicap is that we are approaching the shortest day of the year. It gets dark in New England just after 4 p.m. this time of year, and stays dark for about 15 hours.

"Maybe tomorrow," Tom said optimistically tonight from a candlelit farmhouse on an icy hillside.

It's a sentiment echoed from all over Massachusetts, New Hampshire, and Maine, although power company officials say it may be another week for some towns.

You wouldn't believe how bright the stars are.
