Diatomaceous Earth For Dogs

One of our more exotic ingredients often raises a few eyebrows - Diatomaceous Earth! It’s a unique addition to our amazing dog food which we get lots of questions about. 

Diatomaceous Earth is a non-toxic way to protect your dog from fleas and parasites. And while chemical treatments can cause skin and gut problems, Diatomaceous Earth can actually improve immunity and digestion. It can be used externally for fleas as well as added to food to help protect against internal parasites. So instead of dousing your dog in harmful chemicals, try using this completely natural flea and parasite killer instead!


Diatomaceous Earth (DE) is the fossilised remains of a tiny marine organism called a diatom. They are collected from river and ocean sediment and then purified into a white dust that looks a lot like talcum powder.

It’s only when you look at it under a microscope that you can see what makes it so special. DE has microscopic razor-sharp edges that are really bad news for parasites and insects. Luckily they are so tiny that they are completely harmless for you and your dog.


Diatomaceous Earth can be used to eradicate external pests like fleas, cockroaches, beetles and bedbugs. DE’s sharp edges actually pierce an insect's exoskeleton, humanely killing them on contact. And because it’s a physical rather than chemical mechanism, it doesn’t create environmental toxins. For this reason it’s often used in the rearing of organic animals. 

To use, liberally sprinkle DE powder over your dogs coat and gently rub it in. Repeat over several weeks if necessary, and try not to get any in their eyes or nose as it can cause irritation.

Please remember that like any infestation, it’s essential to completely remove all the offending pests from the home. Sprinkle it on carpet, dog bedding and couches, and leave for an hour before vacuuming it up. Make sure to keep your dogs away while you do this!


DE can also be used to eliminate harmful internal parasites and worms from the digestive tract. Whats more, it can actually improve digestion and immunity! Here’s how it works. As DE moves through the stomach and digestive tract, only a tiny amount is actually absorbed into the body. The rest is flushed out, taking the bad bacteria, fungi, heavy metals, and other toxins with it. Any larger parasites that come into contact with the DE are killed on contact and passed through the urine.

The suggested dosage is 1/2 tablespoon per 5kg bodyweight, fed daily by gently mixing it into their food. Some people like to put it in their dogs water bowl, but we recommend their food as you can control the daily dose. Also note that DE needs to be fed for about 30 consecutive days to be effective, so it’s a long term solution rather than a quick fix.


There are a few grades of DE that you can purchase for home use. Avoid the pool and non-calcined grades (which are toxic), and only use human grade DE.

Purchasing DE is easy, and is considerably cheaper to buy in bulk on the internet. A quick google search will come up with lots of good options. And don’t worry about buying Organic DE, it’s more expensive and exactly the same as the regular human grade DE.
