I've noticed that when I ride or drive X here lately his bowls seem to be 
VERY loose ..... it'll get so bad that it'll be just like icky 
brownish/greenish water down his back legs.   This has been going on since 
I've been working him on a regular basis.
    He seems to be fine in the pasture.  I haven't changed any feed or hay 
...... he gets the same kind of horse "cookies" and carrots as before.  I 
don't seen that runny mess when he's out in the pasture.
    When I'm riding he will stop - expand his belly and sometimes it's gas - 
sometimes it's semi-firm - and sometimes it's really runny ..... like I said 
before, this only seems to happen when I'm riding or driving regularily.
    I've branned him a little extra .... give him corn oil everyday on his 
feed .... have even gotten some of that psyllium (sp) ..... thought maybe it 
was a sand colic type thing.  Other than the 'runnies' he seems to be fine.
    He doesn't really seem nervous riding or driving -- he doesn't shake, 
cowar or any of that stuff you would normally see in a horse that's a little 
on the nervous side.
    Any suggestions???  My vet says he looks fine - but then when the vet 
comes he doesn't demonistrate any of the stuff I tell her that's been 
happening .... maybe he IS nervous and just doesn't "show" it any other way 
..... whatchya'll think??
