Saddle Tree Types and Pressure Distribution

Modern saddles provide new options for tree type, with the goal of sparing a horse pain from localized saddle pressure. But new Swiss research suggests that, at least when a horse trots, tree type makes little difference in pressure distribution alon Read More

FEI Proposes Prohibited Substances List Modification

Some non-steroidal anti-inflammatory drugs at low therapeutic levels might be helpful for horses with inflammation between competitions, so clearer and more current information is needed about detection times for anti-doping testing, accordi Read More

"Conflict Behavior" Evaluation Varies Among Horse Professionals

There's a new term that describes the actions of our horses in response to our unclear cues or handling: "conflict behavior." Horses showing conflict behavior might buck, rear, toss their heads, gape their mouths, or try to escape their handlers, to Read More

Piroplasmosis: Searching for Answers in Europe

The number of piroplasmosis-positive horses imported from Europe varies considerably from one country to another, according to new findings by Swiss researchers. With piroplasmosis steadily creeping across the globe in the 21st centu Read More

Training: Food Rewards Are More Effective Than Physical Contact

Everybody loves a good back scratch, including your horse, right? Scratching of the withers has been scientifically proven to reduce a horse's heart rate, but a good scratch might not be enough to communicate to your horse that you're h Read More

Seeking Solutions to Separation Anxiety

When teaching young horses to accept separation from their pasturemates, it might seem like a good idea to train them in pairs first for a while before training them alone. However, new equitation science research suggests that pairing them up might Read More
