Subtle signs may indicate more serious issues.

By Boehringer Ingelheim

Have you ever spent time with your horse and thought, “Something just isn’t right. Why is my horse so irritated? What’s got the horse in such a bad mood?” It could be little things like pinning their ears while being groomed or kicking out when the girth is tightened or refusing a jump they normally take without issue. When these types of behaviors start to establish a pattern, they may be a sign that there is a bigger issue.

Your horse’s “bad behavior” could be subtle signs of equine stomach ulcers, and it may warrant a call to your veterinarian.

Inappetence, signs of colic and poor body condition are often associated with gastric ulcers, however, changes in behavior may also be suggestive signs.

“The presence of equine stomach ulcers isn’t always obvious,” says Hoyt Cheramie, DVM, MS, DACVS, Senior Equine Professional Service Veterinarian, Boehringer Ingelheim. “Sometimes abnormal behavior doesn’t signify a larger attitude issue or a need for additional training – it may just be the horse’s way of showing they don’t feel well.”

All horses are at risk for stomach ulcers. Two out of three competitive horses have them. Anywhere there is stress, stomach ulcers may be a risk. Stress comes from many sources, such as frequent trailering, intense training and loud, unfamiliar noises at the showgrounds.

And it’s not just those that show. Non-competitive horses are also susceptible as 30 percent of pleasure horses have ulcers.

Ulcers form when excess acid builds within a horse’s stomach. Horses naturally produce acid – up to 16 gallons per day – that helps maintain regular gastric function. But stress, feed routines and other management practices can cause acid to rise above normal levels and damage unprotected stomach lining, resulting in ulcers.

Unfortunately, ulcers can’t be seen with the naked eye so there’s no way to reliably make the call yourself. The only way to diagnose them definitively is for a veterinarian to perform a gastroscopy.

If ulcers are detected during a scoping, treatment with GASTROGARD® (omeprazole), by Merial, may be recommended. GASTROGARD is the only proven and FDA-approved ulcer treatment product. It contains specially formulated omeprazole that suppresses acid production to a level that allows the ulcers to heal.

In addition to treating with medication, Cheramie suggests the following to help manage ulcers:

· Providing continuous access to roughage through grazing or hay-restrictive feeders or nets

· Dividing grain-based feed into multiple small daily meals

· Working with your veterinarian to make other necessary adjustments

“Along with good management practices, you can also work to prevent ulcers with

ULCERGARD® (omeprazole), by Merial, especially during times of stress,” Cheramie says. “Proven to help protect your horse’s stomach lining, its patented formulation allows the omeprazole reach the small intestine for absorption without being broken down by stomach acid.”

Don’t make excuses for your horse’s irregular attitude when stomach ulcers could be to blame. Instead, talk to your veterinarian about scheduling a scoping. If ulcers are indeed the culprit, he or she can recommend steps to help your horse feel, perform and behave their best.
