Are you saying I can give mms to him orally and 1 drop  ( unactivated) in the eye?
I've got a 6 qt. water dish that 3 dogs and several cats share.  Would it be ok to add the mms to the shared water dish?  how many drops would I need for a 6t qt dish?  There is no way I could figure out the mms dosage. 
Oh, and thank you very much for the reply and advice.
