When A horse that is freucently excersiced what do they need?

Horses, like people, will build muscle tone and endurance as they work. Be sure to step them up gradually so that they don't get injured or sore, but there's really little to do differently than a horse that's rarely work. There's nothing you absolute must do, but consider three suggestions (you may or may not actually need them, but be prepared):

1. Make sure the horse has acess to plenty of water, and give him breaks to drink during long workouts. This is the simplest thing you could do for your horse, but it's very important during the summer months.

2. You might want to consider suppliments. These will simply make sure your horse is getting 100% of the nutrients he needs for hard work, and the less expensive versions can cost as low as $5 a month. My favorite would be Electrolytes or Apple-Dex--both are designed supply the electrolytes working horses lose.

Also, depending on the horse and the type of work he's engaged in, joint supplements can help keep his joints (especially hocks and fetlocks) healthy longer. Or if he already has mild Arthritis or a similar condition, these will help ease stiffness and pain. It's normally not nessesary, but for hard trail riding or higher level dressage/jumping, it probably will help.

3. Okay, the last thing is feet. A lot of riding (especially on hard surfaces) will wear down hooves faster than they can grow. Make sure to schedule regular farriar visits and keep in mind that, depending on your horse, you almost definitely will need shoes (which can add up to 90 or so dollars to your farriar bill).
