I am not sure about the iodine doseage - you might try asking Trapper about that. As far as colloidal silver, you can give plenty of it especially over the short term. If it were me I would give several tablespoons per day in the drinking water. Other pet owners report that their pets prefer water with colloidal silver over plain water and they also report that their pets have renewed energy and friskiness such as they have not seen for years. The combination of colloidal silver, inositol/IP6 and oleander extract appears to be a very good one for pets as well as humans. Again, start off with very tiny amounts of oleander and gradually work your way up.
