If your horse has a cough that persists into exercise or is heard while your equine friend is at rest in the barn, be sure to talk to your veterinarian about evaluating your horse for respiratory disease. It could be a problem with the upper airway (the nasal passages and throat) or the lower airway (the lungs).

While waiting for your appointment, try decreasing your horse’s exposure to dust, as that is a primary trigger for lower respiratory disease such as asthma or heaves.

Some simple things you can do include avoiding straw bedding, not using a leaf blower on barn aisles, and not storing hay or bedding above your horse’s stall. Last but not least, while us humans may be more comfortable with all the barn doors closed on colder days, your horses’ lungs will appreciate open doors/windows and good ventilation!

As always, if you have questions or would like to learn more about preserving your horse’s respiratory health, your equine veterinarian remains your best source of information!

🤔 What is "Slobbers" in Horses? 🐴

If you've noticed your horse drooling excessively, it could be due to slobbers—a condition caused by a compound produced by a fungus that grows on red clover 🍀.

🔍 You can spot the fungus by checking the underside of red clover leaves—look for tiny black dots. It thrives in hot, humid weather and can affect horses grazing on fresh pasture or eating infected hay.

👉 While slobbers may look alarming, it’s usually harmless as long as your horse stays hydrated 💧.

Here's some interesting information about Polysaccharide storage myopathy (PSSM) from our friends at Rhinebeck Equine. Have you heard about this condition before? Let us know in the comments below!

"💪🏼 Last week, we discussed Exertional Rhabdomyolysis (ER) aka tying-up. We mentioned that PSSM (Polysaccharide storage myopathy) is associated with genetic susceptibility of ER.

💪🏼 What is PSSM?
PSSM is a disorder that causes muscle soreness and tying up in horses from abnormal glycogen storage in the muscles. The two types of PSSM are Type 1 and Type 2.

♦️ PSSM Type 1 is caused by a mutation in the GYS1 gene (glycogen synthase 1). The mutation causes muscle cells to produce glycogen continually. PSSM Type 1 is more commonly observed in Quarter Horses, Paints, Appaloosas and draft breeds; however, it has been documented in 20 breeds.

♦️ PSSM Type 2 occurs without genetic mutation yet results in abnormal glycogen storage in the muscles. It is still unknown the exact cause of PSSM Type 2. PSSM Type 2 is more common in warmbloods, but it has been linked to other breeds.

🩺 What are the clinical signs?
Sweating, lameness, sore muscles, weakness, undiagnosed lameness, poor performance, and muscle tremors that may occur with or without exercise. Not all horses will exhibit severe clinical signs.

🥼 How do we test for PSSM Type 1 and 2?
Testing for PSSM Type 1 requires hair samples with the roots attached to test for the GYS1 variant. Testing for PSSM Type 2 requires a muscle biopsy.

🩸 Additional testing of insulin may be warranted due to PSSM Type 1 horses are commonly more sensitive to it. Insulin causes the GYS1 gene to produce more glycogen.

💪🏼 How do we treat PSSM once diagnosis is made?
Diet and regular exercise are crucial to managing these horses. Often these horses are on a low non-structural carbohydrate (NSC) grass hay and a ration balancer. However, each horse is an individual and may need more calories which can be achieved by adding a low-NSC or high fat feed. Additional supportive care may be necessary during an active episode of tying up.

🤔 What is the prognosis?
Sadly, there’s no cure, but with dietary and exercise management horses can do well and reduce the frequency of active tying-up episodes."

If you have any concerns about your horse exhibiting signs of PSSM Type 1 or 2, talk to your veterinarian.
