Horses are very proficient sweaters, making them some of the most efficient animals at cooling themselves — but they are still at risk for heat stress. There are many ways we can help them sidestep this risk as the temperatures heat up. Below, I’ll cover diminished electrolytes, groups of horses at greater risk, signs of heat stress, and tips to keep your horses safe. 

Everybody loves to see a donkey! With their large fuzzy ears and soulful eyes, they naturally tug at the heartstrings of horse lovers everywhere. Donkeys were first domesticated in Africa around 3000 BC. They evolved in desert areas and, consequently, developed as browsers that can adapt to poor quality feed and irregular water supplies. Their easygoing nature and hardiness made them ideal as beasts of burden in the hotter, drier parts of the world. Coming in a variety of sizes, donkeys and their hybrid offspring, mules and hinnies, range anywhere from Miniature donkeys of less than 35 inches in height all the way up to Mammoth Jack donkeys that can exceed 15 hands.

If you have ever evaluated your horse’s ration or tried to calculate an appropriate dose of dewormer for a growing horse, you will know that accurate estimation of your horse’s body weight is important for meaningful results. While we all know that a mechanical or digital scale is probably the best way to evaluate the weight of your horse, not many of us have convenient access to one. Horse owners do have access to other tools for estimating the body weight of their horses. Weight tapes, for example, are inexpensive and readily obtainable at most feed stores.

Polysaccharide storage myopathy or PSSM is a muscle disease that occurs primarily in horses with Quarter Horse bloodlines such as Quarter Horses, Paint Horses, and Appaloosas. PSSM also occurs in other breeds including Drafts, Draft crossbreeds, and Warmbloods. The primary clinical sign of this disease is muscle cramping or tying-up; however, clinical signs may vary with different breeds and severity. There are several different abbreviations used to describe polysaccharide storage myopathy including PSSM, EPSM and EPSSM. Tying-up also occurs in other breeds of horses such as Thoroughbreds and Standardbreds, but this form of tying-up has a different cause.
