 How is a blood test most accurate for dehydration? 
 Wouldn't the horse have to have a "pre-ride" CBC to
 compare the diagnostic test to?>

Not necessarily. Total Protein is a good indicator when combined with an 
abnormally high PCV. Also, the science says that a 3% loss of total body 
weight during endurance exercise is an indicator of the approach of severe 
dehydration and a harbinger of gut water uptake reduction.

Different strokes for different folks.

Horses aren't as obedient as humans in that regard.

I'll let you know how it turns out.
