Understanding PPID in Horses: Early Detection, Long-Term Health

If you’ve noticed your older horse slowing down, not shedding out like they used to, or just not seeming quite themselves, you’re not alone—and you’re not imagining it either. These could be early signs of Pituitary Pars Intermedia Dysfunction (PPID), a common hormonal condition that affects many aging horses.
At Advanced Equine of the Hudson Valley, we’re here to help you understand what PPID is, what to watch for, and how we can work together to support your horse’s health and comfort through every stage of life.

What Is PPID in Horses?

PPID is a disorder of the pituitary gland, a tiny but important part of your horse’s brain that helps regulate hormones. As some horses get older, changes in the brain reduce its ability to control this gland properly, which causes an overproduction of hormones—especially ACTH. These hormonal shifts can affect everything from immune function to metabolism to hoof health.
You may have heard PPID referred to as Equine Cushing’s Disease—and while the term is a bit outdated, the concerns are still very real.

How Does PPID Affect Horses?

Because PPID affects so many systems in the body, its symptoms can vary widely. Some horses might seem a little off or age more rapidly, while others develop more obvious issues like repeated infections or laminitis. The tricky part? Many early signs are easy to mistake for “normal aging.”
Here are a few common things we see in horses with PPID:

• A thick, curly, or long-haired coat that doesn’t shed properly
• Muscle loss, especially along the topline
• Increased drinking and urination
• Slow wound healing or recurring skin infections
• Chronic high intestinal parasites levels
• A dull or depressed attitude
• Hoof sensitivity or repeated bouts of laminitis
• Unexpected weight loss or a pot-bellied appearance

If your horse is over 15 and showing any of these signs—or even if they’re just not quite acting like their usual self—it’s worth looking into.

The Importance of Testing for PPID in Your Aging Equine Companion

The only way to know for sure if your horse has PPID is through testing. A simple blood test measuring ACTH levels can provide important insight into what’s going on beneath the surface. Often we will also recommend second level test called the Thyrotropin Releasing Hormone (TRH) stimulation test.
Catching PPID early makes a world of difference. It allows us to start treatment before serious complications arise, and it gives you the peace of mind that comes from knowing what your horse needs and how to support them.
At Advanced Equine, we offer easy, reliable testing either at the clinic or at your barn. If your horse is entering their senior years, we recommend making PPID screening part of their routine wellness care.

Can PPID Be Treated?

Yes—while there’s no cure, PPID is absolutely manageable, especially when it’s caught early. Most horses respond well to treatment and go on to enjoy happy, active lives.

Treatment usually involves:

 

– Daily medication (typically prascend) to help regulate hormone levels

– Regular follow-ups and bloodwork to monitor how your horse is doing

– Supportive care like dental exams, hoof care, and parasite control

– Dietary adjustments to reduce inflammation and prevent laminitis

Every horse is different, and we’ll work with you to build a treatment plan that fits your horse’s unique needs, lifestyle, and personality.
