Has anyone had any problems with horses and goiters. I
have one that seems to come and go.One day it'll be the size of
a walnut, the next day it'll be gone. I have him on minerals
with iodine in it. One vet suggested taking him and having 
a test done which is done over a period of time. Had a thyroid
blood test done and it came back normal, was told this isn't
really a good indicator. Another vet said that he has seen 
horses with them frequently and didn't seemed concerned. Any input would be appreciated.
