Daily turnout is another way to ensure that the horse receives regular exercise, and is certainly important for maintaining good spirits. Here are some points to bear in mind. First, preserving soundness is a very important consideration. Unfortunately, the years of wear and tear inevitably take their toll, and some level of aches and pains is the norm rather than the exception. It's a good idea to ask your veterinarian to examine your older horse before putting the previously idle horse back into work.
Workouts Start out slow and err on the side of caution.
Try to vary the workouts as much as possible to maintain the horse's interest. Be cautious during the hot summer months, particularly when beginning training during the summer. Older humans and animals are often less able to lose body heat during exercise, in part because of a decline in cardiovascular performance and a reduction in sweat gland function. In hot weather, actively cool the horse after exercise by applying cold water over the neck and body. Also allow him to drink a moderate amount of water after exercise to replace fluid losses due to sweating.
