Thain Johnston – September 28, 2018:
I have been using permanent guard as a daily dietary supplement in my dog’s food for 6 years. We are poodle breeders and I have not had to use toxic worming meds once since I started with the DE. That is in around 100 dogs. NO TOXIC WORMING MEDS NEEDED!!
My dogs also have fantastic skin and coats. We also use it to kill bugs in the house and garden. I can’t say enough good things about DE. I consider it a wonder substance. Also after researching all the different DE sources there are , there is no question that Perma guard stands alone as the highest quality product available.
