on the subject of sand colic...your horses don't have to be on sand to
develop a problem. I just had a 'sand impaction' surgery on one of my ponies.
they took out a large amount of dirt.
I treat the guys that are on a dirt surface with the psyllium for 7 days
once a month, every month. the horses that are on grassier surfaces I treat also
but not as often. it is a catch 22 with the ponies...they cant be on grass due
to foundering issues, so they need to be maintained because of the dirt. Sam's
club/walmart has their brand so it makes it very affordable.
