My main question is about the montmorillonite clay. And its function in raw dog food.
According to their website, this ingredient is defined as:
Montmorillonite is a clay that is primarily colloidal silicate, which contains over 50 ultra-trace mineral compounds including Antimony, Barium, Beryllium, Boron, Bromine, Cadmium, Carbon, Cerium, Cesium, Chloride, Chromium, Cobalt, Copper, Dysprosium, Fluoride, Gadolinium, Gallium, Germanium, Iodine, Lanthanum, Lithium, Manganese, Neodymium, Nickel, Phosphorus, Rhenium, Rubidium, Samarium, Scandium, Silicon, Silver, Strontium, Sulfur, Tellurium, Thallium, Thorium, Tin, Titanium, Vanadium, Ytterbium, Yttrium, Zinc, and Zirconium. Feed studies by the Veterinary Medical Diagnostics Laboratory at Texas A&M University have shown that Montmorillonite clays can sequester (bind) aflatoxins contained in grains and oilseeds.
Wikipedia has this:
Other uses include as an anti-caking agent in animal feed
And complete mineral data for montmorillonite here.
The dogs did enjoy these medallions, though.
