<< Major <cannot> dissapate heat well at all.  He comes into a check
 panting, and needs 5-10 minutes (at least) to come down to criteria even
 if he is in excellent shape.  We have to choose cool weather rides and
 ride him conservatively.  While he looks more TB than QH, and his muscle
 mass is sleaker than Rocket, he pants and holds heat.  We aren't sure
 how much is related to his breeding and how much to his unfortunate
 choice of color.  >>
