Dehydration is one of the most common health concerns in horses, especially in the winter when water sources are subject to freezing; additionally horses performing strenuous exercise in hot weather are at risk.  Dehydration can lead to several health problems including impaction colic, reduced feed intake, decreased blood volume and circulation, and increased heart rate.  One of the easiest methods for checking if a horse is dehydrated is by gently pulling the loose skin away from its neck, holding it for a few seconds, then letting it go.  A hydrated horse’s skin will immediately return to being flush with the neck.  A dehydrated horse’s skin will take longer to return to its normal position.  The rate at which the skin returns to its normal position will indicate how dehydrated the horse is.
