Summer months usually means more hours in the trailer and an increase in the number of days and nights away from home for our horses. Proper hydration is essential for a horse to maintain normal fluid-electrolyte balance for their health and optimum performance. Electrolytes come in three forms. Horse owners may choose to use the powder form that is mixed with water and then consumed by the horse over time. Some horse owners prefer the paste form of electrolytes for instant delivery and so they may be assured of the time and amount of electrolytes the horse has ingested.
