Diatomaceous Earth, also called “DE”, is made of microscopic silica shell remains called diatoms. These tiny particles actually cut up the parasites when they come into contact with them, thus killing them. The dog's digestive tract then passes them out. We use natural food grade DE (not the swimming pool grade). The difference is that pool DE is chemically treated and partially melted and contains crystalline silica which can cause respiratory irritation. Natural DE is mined, ground, sifted and bagged and contains non-crystalline silica, which is not considered a hazard according to the National Institute for Occupational Safety and Health. EPA allows it’s use in food storage and processing areas. DE has many uses from insect control to animal de-worming. It is not the fastest acting insect control but it does work and is non-toxic.

Suggested feeding rate: is 1 TBSP per 50# body weight, stirred in food. Maximum 2 TBSP daily. Feed 3 consecutive days monthly when used as a wormer.
