dogs dont sweat so you dont have to worry about turning her blue with too large particles. it is easy to set up electrolysis with two silver bars and four 9v batteries. if on the cheap, get one ounce rectangle and cut it length way down the middle. viola, two pieces. you can also get by with three 9v or even two. they hook together in a series by snapping together. use glass jars and distilled water. only the silver bars go in the water using alligator clips. to make a quart, let it run for four to six hours. thats it. you can do this for years, whenever you need some. keep everything contamination free. rinse with distilled, clean with distilled. keep it all clean. touch no metal. keep magnets and electrical current away from it. store in amber glass in a cool dark place. its really easy.
for an alternative or for quality instead of quantity, go to Utopia-Silver . it will take much less because it is more effective. i highly recommend it and the price is decent.
