Get 100 Percent – Your Horse's Health Depends on It

As a horse owner, you want the best health care possible for your horse – and in turn, you want your horse to give 100 percent effort. But are the products you are giving your horse 100 percent of what they claim to be?

Recently, horse owners using some alleged equine ulcer prevention or treatment products have been unpleasantly surprised to learn the ingredients in some products just didn't add up to their label claims. This information came to light when the U.S. Food and Drug Administration (FDA) tested them. In fact, one of the products, Gastroade Xtra, only contained 36.3 percent of the label claim.1 Another, Omeprazole Oral Paste, was tested and found to be sub-potent at just 68.1 percent of the label claim.2

Custom-designed Pieces a Labor of Love

When Judy Wagner of Montana Silversmiths has the privilege of presenting a championship buckle, she says it sends shivers down her spine.

"Being admitted to the profession of veterinary medicine, I solemnly swear to use my scientific knowledge and skills for the benefit of society through the protection of animal health (and) the relief of animal suffering. …"
–Veterinary oath

The ability of the veterinarian to relieve animal suffering has made enormous advances in the past 50 years. Our understanding of disease processes, the development and refinement of surgical techniques and our diagnostic abilities have been vastly improved over recent decades. Imagine what James Herriot would think of digital radiography or MRI. It's a great day to be a veterinarian!

Think Twice Before Vaccinating a Horse Yourself: Playing Veterinarian May Not be Worth the Risk

Let's face it, horse ownership can be expensive! So it's no surprise that horse owners everywhere are looking for ways to pinch pennies. But not using a veterinarian to administer vaccines is not the place to cut back. Megan Green, DVM, manager, Equine and Large Animal Veterinary Services, Merial, explains the reasons why.

It's Show Season. Bring Your A-Game.

Long hours in the saddle……trailering to lessons……scrimping and saving to pay for show fees……cleaning tack……body clipping……polishing hooves. The preparation work for the first show of the season is time-consuming and sometimes tedious. But equine enthusiasts around the country could not imagine spending their time doing anything else right now – that show is right around the corner.

Top Quarter Horse Trainer Knows the Value of Preventive Equine Health Care

When Pete Kyle, of Kyle Ranch in Whitesboro, Texas, starts planning his competition year, like any good trainer, he considers multiple variables – his amateur rider's goals, the individual horse's current level of training, conditioning time and show scheduling. While all of those are important, there's another – keeping his show string healthy throughout the entire show season.

Make the Call: Laminitis 911 and the First Veterinary Examination

Your horse is lame. Very lame. It's time to call the vet. What happens next? You've been watching your horse closely. At first you weren't sure; maybe he was just stiff. But this morning you know something more than that is wrong. You had to pull him out of his stall. He didn't want to turn around to be clipped into the crossties. He's shifting his weight. When he does walk, he looks like he's leaning back on his heels.

Caring for Your Equine Athlete During Long Shows

Common problems that are encountered at equestrian events can be broken down into two broad categories - medical problems and musculoskeletal problems.

Acupuncture: When Is This Alternative Medicine Practice Right for Your Horse?

When you think of acupuncture, you probably think of needles and pain. You may even be a bit skeptical about the practice and its effectiveness. However, there may be a place for acupuncture in your horse's health protocol. We asked Megan Green, DVM, Manager, Equine Large Animal Veterinary Services, Merial, and a Certified Veterinary Acupuncturist some questions about acupuncture and when it might be considered appropriate.

What to Expect from a Pre-Purchase Examination

Ready to make an offer on the horse of your dreams and ride off into the sunset? Or perhaps go win that championship ribbon you've been pursuing for so long?

Why spend several hundred to more than a thousand (depending on the number of radiographs) on a pre-purchase examination, especially if you're familiar with the horse and its owner or trainer?

Equine Stomach Ulcers: A Threat to Horses of All Ages

Q. I have several young horses in my care that aren't in training yet. Is it possible for them to get equine stomach ulcers?

A. You're smart to ask that question. We often think our young horses are immune to equine stomach ulcers because they aren't often exposed to the stressors that we know can contribute to the development of ulcers. Those stressors are more often associated with the kinds of activities we do with competing horses such as training, traveling and trailering.

Reining Trainer Uses Care When Bringing Along Young Horses

Once Sebastian Petroll arrived from Germany in 2001, it didn't take long for him to become a household name in reining circles. In fact, since then, not only has he captured multiple Level 1 and 2 titles and become a sought-after trainer, but he's also earned his National Reining Horse Association (NRHA) judge's card and most recently was named to the NRHA Board of Directors and the Stewards Committee.

What's led to his arena success and the recognition by his peers? Petroll trains his horses for longevity and has developed a reputation for having horses that last. "These Futurity and Derby horses are just two-year-olds when we start them – and keeping that in mind for every aspect of training is really important," Petroll says. "We want them strong – mind and body – not just for their Futurity and Derby years, but for a really long time."
