I'm really glad this thread 
    started, as I was wondering the same thing yesterday.  Of my two boys, 
    PG has less fat than Toc, and has  leaner kind of muscle mass (I know 
    there is a scientific way of putting this, but I'm damned if I know it) : 
    Toc is built like a weight-lifter, PG like a swimmer, if you get the 
    picture.
     
     
    What I find fascinating is 
    that PG has shed all of his winter coat already, but Toc's, whilst not long, 
    is still thicker than PG's.  Both are blanketed the same, and kept in a 
    barn, so lights can't really be a factor.  Could it be the type of 
    muscle each has developed, or the fact that PG has less obvious body fat 
    than Porky?
     
     
    And as for hosing horses in cold weather - I 
    was told by an old Irish horsewoman that, if you are going to do it, use 
    cold rather than warm water as the latter opens the pores, and the horse 
    feels cold later.  I have a brilliant 
    rug which I use after hosing - it has a sweat sheet inside, and a day sheet 
    outside, so it wicks off the water and keeps them warm.
     
     
    But I still maintain that you can achieve 
    the same results with patience and elbow grease.

    My not so scientific theory on this is 
    that the "engine" or muscles of the horse are what keep them 
    warm...so the more conditioned animal would generate more warmth because it 
    actually burns the fuel/food it is given thereby creating heat.  The 
    fat animal doesn't need the calories and possibly just stores or dumps most 
    of them instead of burning them....thereby creating a lot less heat.  
    Hmmm.....not a bad theory when I reread it. LOL

        I wonder if the better 
        conditioned horses were warmer because they/you/me/us have better 
        circulation if we are in good condition, less body fat etc.
