These are dosages from a clinic that treats animals holisticaly and uses there own 10ppm CS.
Serving Size: Dogs: 70 to 120# canines can tolerate 1 to 2 tbsp. of Colloidal Silver 3x/daily during illness. Smaller dogs can take a smaller dose than large dogs. 1/2 to 1 tsp. 3x/day for a dog 20 to 40#'s. 1/4 to 1/2 tsp. 3x/day for smaller dogs
Kittens and adult cats can tolerate 100% 10 ppm CS/EIS as their sole source of drinking water, if desired. 10 to 20 drops 3x/day works as well.
Hope that helps
Steve
PS When my dog is sick I give it straight 10ppm CS with no problems.
