What's the cost of the product

I read on here where some guy use's it on his feed as a wormer mixes 40lb to 100 lbs of dog food

It is safe to sprinkle on food and will help function as a wormer. I use it as a supplement to worming.
I also sprinkle it in the kennels. Helps with flies & fleas as well.
Hope this helps.

there are two different kinds of DE. one kind is labeled food grade that is the kind that is safe to eat. there is also another kind of DE that is hazard to humans and animals. so look for that food grade on the label if you sprinkle on dogs food.
