Cushing’s Disease
Is your older horse taking longer to shed out than usual this spring? Is it getting harder to keep weight on the old man? Has your retiree had more than one hoof abscess in the last year? If so, you may be dealing with PPID, better known as Cushing’s Disease. Read on to learn more about PPID from this wise old cat!
What is PPID?
PPID stands for Pituitary Pars Intermedia Dysfunction, which is the technical term for Cushing’s disease in horses. In the most basic sense, PPID is a brain tumor. The brain actually has a very intricate system of glands that produce hormones which stimulate additional glands to produce other hormones that control functions elsewhere in the body. When one of these glands (the Pituitary) in the horse’s brain goes AWOL, you have Cushing’s disease.
The tumor growing on the pituitary gland is called an adenoma. This tumor applies pressure to the gland as it grows, causing over-production of its hormones (namely, adrenocorticotropic hormone, or ACTH). The clinical signs of Cushing’s disease in horses are all a result of too much ACTH in circulation. Time for a nap break…all of these letters are giving this cat a headache!
What are the signs of PPID?
Cushing’s disease can lead to a bunch of problems. For one, overproduction of ACTH can confound the whole winter-coat-growing system, so your horse winds up with long, curly hair in the hottest summer months. Failure to shed out completely or in a timely manner is the most well-known sign of Cushing’s disease. However, now that we know early treatment seems to slow the progression of the disease, our efforts are aimed at diagnosing the disease earlier, using more subtle signs.
In the early stages of the disease, PPID can cause lethargy, muscle wasting, regional fat deposits, recurrent infections, increased water consumption, and increased urination. The most worrisome side effect of Cushing’s disease is chronic laminitis. There is no known cure for laminitis, and it can even be life-threatening in horses with PPID. And that’s bad, because horses have 8 fewer lives than us cats.

How do I know if my horse has PPID?
Since the early signs of the disease can be subtle, our docs recommend annual testing for Cushing’s disease on any horse over 10 years of age. First the docs will draw blood, then it goes on a trip to Cornell University where they test the ACTH levels. Then, the doctors will compare your horse’s ACTH levels to the normal range for a horse during that time of year.
Considering your horse’s test results and clinical signs, your vet may recommend daily medication to treat PPID. Luckily, the folks at Boehringer Ingelheim have come up with a great medicine called Prascend that is easy to give, and works really well too! Just one tablet a day mixed in with grain is a sufficient dose for most horses. I’ve heard it tastes better than the cheese-flavored medicine the humans squirt in my mouth every day.
Conveniently, I have an event coming up here next week at Springhill Equine on Wednesday April 19th at 6:30pm, where you can learn all you ever wanted to know about PPID and other senior horse problems! Some of my favorite people from Boehringer Ingelheim will be there to answer any questions you may have, and best of all there will be food! Oh, and a chance to win a free ACTH test for your horse. You may think that is even better than food, but that’s where we will have to agree to disagree………
See you there!

Garbage in, garbage out, or so I hear from the humans. Here I sit munching on a nice grasshopper. They have a great flavor; I recommend you try them, especially roasted with a bit of salt and pepper! Great nutritional choices like this are what keep this cat in top physical condition. Senior feeding strategies for your horse will keep them running at peak performance, too.
Ch-ch-ch-changes
You sang it, didn’t you? I know I did. Then I had images of the movie Shrek play through my head. OK, back on track. You have made wise decisions for your horse’s diet (your own, not so much) and things have been going great. However, as horses get older, their diet needs change, and those changes are very different from the ones humans experience. Doing a very thorough evaluation of body condition score, muscle quality, and diet should be done at least every six months on every horse. (Need help? My minion, Beth, has tons of nutrition experience and can help you formulate a custom plan. In fact, Wellness Plans include this!) If you notice topline shrinking, maybe the ribs are a little easier (or harder) to find, or eating is taking a long time, it may be time to adjust the diet.
Protein, Protein, Protein
You’ve been monitoring your horse’s condition, and have noticed the muscles on the topline are slowly fading away. Maybe there are fat pads cropping up by the top of the tail and behind the shoulder blades. It’s just plain harder to maintain condition. Protein is the answer. Well, part of the answer, anyway.
We have been well trained not to increase protein for older people and animals, but, as usual, horses are weird. It’s important to remember that basic diets for horses are pretty low in protein, usually around 10-12%, versus cat diets which hover around 30-32% protein. This means adding protein to equine diets is a relative thing. The easiest way to add protein is with a ration balancer. Just about every major feed company makes a ration balancer. Enrich Plus, Triple Crown 30, Equalizer, and Empower Balance are all examples of ration balancers. Adding a pound or two of one of these to every feeding is often all the older guys need.
When do I switch to Senior Feed?
Maybe never. While 15 years old is our guideline for Super Senior, it’s just that: a guideline. Dr. Lacher’s 27 year old horse is still on a “regular” feed, SafeChoice Maintenance. Full on Senior concentrates are best suited for horses with very bad teeth. These diets are designed to meet all the nutritional needs of a horse: grain, roughage, vitamins, and minerals. Most of our Seniors have pretty good teeth which means they can get loads of nutrition from hay. As long as your Super Senior is doing well on a regular diet, there’s no need to switch to senior feed.
If not Senior feed, then what?
Okay, you’re having some trouble maintaining topline, but there’s also some fat pads creeping up beside your horse’s tailhead, and you currently feed SafeChoice Maintenance and coastal hay, along with 4-5 pounds of alfalfa hay. Oh, and your horse just turned 17 years old. You ride 3-5 days every week and would put yourself in the moderately in-shape category. Now what?
There’s loads of options out there, but a little tweaking will go a long way here. First, let’s increase the quality and quantity of protein. Dropping back on the amount of SafeChoice Maintenance and adding Empower Balance will increase protein while decreasing calories overall. Trying this simple change for 30 days, while monitoring body condition, may be all the adjusting that’s needed. However, if you aren’t satisfied after 30 days, we can tweak the hay choices, or even switch concentrates all together. My point is: You’ve got options and I’ve got minions to help you with those options.
