    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.

    We are a Purebred Havanese breeder, my dogs are now retired. I wanted to convey that we used DE in their food. And, that my puppies for sale, were parasite/worm free. I even received a call from one of my clients wanting to let me know that her Vet was very pleased with the health of the puppy and was surprised that, when tested, the puppy had no worms. We also used it in the garden to get rid of pests on potato and tomato plants. It worked amazingly well. Something that it works well on, as well, is bed bugs. When purchased our home we inherited bed bugs, I immediately dusted the bed, washed the linen in hot water, and more importantly sprayed the DE under baseboards, etc. where they hide. Got rid of the problem fast and safely.

    Have been a customer for years, a trusted source of high quality DE. Good pricing, even with shipping the 50 lb bag is cheaper than the DE on Amazon.
