Yeah any change and my mare has the smae problem, I hada vet tell me they suspected it after I told him about what I saw and how she acted and then my trainer said she mite, So I got the smartGut to see if she acts or looks like she feels better, I she digests things better gets a littler perkier and stuff. If my trainer nad I think she still has them ater I am out of the amount I got we will call the vet.
