I read about using Colloidal Silver to help with my dog's teeth. His teeth were dark and full of plaque; I couldn't brush them well enough and they bled. Winston has an underbite and his teeth looked brown.

I use 1/2 tsp. Colloidal Silver per dish of water and add to his water about once per day. I don't add more until he drinks the whole thing. He weighs 35 lbs. I just got a non-name brand C.S. and it seems to work great!
