Dallas Goble, DVM, thinks quite highly of run-in sheds. “They offer better quality health for the horse than enclosed barns,” says the associate professor of surgery, College of Veterinary Medicine, University of Tennessee. “Run-in sheds have better ventilation and less accumulation of dust mold and spores than what accumulate in a normal barn. They’re relatively safe–very few injuries are associated with sheds that are maintained in good condition. Individual horses have the opportunity to regulate where they want to be, and that’s good for the horse’s health and psychological well-being. Run-in sheds allow horses to act more like real horses. They’re very horse friendly.”

But for run-in sheds to provide maximum safety and protection, it’s critical they be constructed and sited properly.


Siting The Shed


Probably the first consideration for your run-in shed is to identify the best place for it to be built. It should be located in an area that offers good drainage so horses aren’t standing in muck and dirty water. Says Raymond, “Often there is a lot of activity at the shed, especially if you have hay there, so it can become quite m
