Just don't let your male dogs into it. We lived for a time in Fort Rock OR, where a lot of the DE is mined. My little rat terrier would spend his time trying to catch all the sage rats that lived everywhere. Took him about 6 months and he developed Silica kidney stones. I was told by the vet there that it was common in earth dogs of the area because they eat so much of the DE while digging things up.
Needless to say, I don't use it anywhere. The lesson was very expensive.
