Some horses, especially some of the European breeds and ponies, retain their winter coats longer than we’d like regardless of how much you groom them or attempt to accelerate the process with a shedding blade. If they are just a pasture pet or in very limited work it’s fine to let the process take it’s time (although it’s messy and that extra fur can trap dirt, sweat, mud, etc). But if they are in daily work and/or showing, especially in a warm climate, then even a little too much extra coat can cause BIG problems…primarily overheating during work or difficult/delayed cooling-off time after they work. Even after a bath, they are slow to dry and slow to cool.
Body-clipping, when done properly, has no harmful effect on the eventual summer coat. But it sure does make those furry horses more comfortable! Especially when it’s done by an experienced body-clipper who knows how to prep the coat, gets the job done fast and uses sharp blades.
