FAQ: How Often Should I Apply Diatomaceous Earth to My Dog?

Many pet owners today have switched to natural remedies to keep their furry friends healthy and free of pests. One of the most popular natural remedies is diatomaceous earth, which is a fine powder made from fossilized aquatic organisms known as diatoms. Diatomaceous earth has many uses, from removing toxins and parasites to improving digestion, but how often should you apply diatomaceous earth to your dog?

What is diatomaceous earth?

Diatomaceous earth is composed of the skeletal remains of microscopic organisms known as diatoms. These organisms have been dead for millions of years, leaving behind their silica shells which are ground into a fine powder. Diatomaceous earth is a natural substance that is non-toxic and safe for use around pets and humans.

How does diatomaceous earth work?

When diatomaceous earth is applied to a dog’s fur or skin, it acts as an abrasive agent, scraping away at the exoskeleton of fleas, ticks, and other pests. As a result, these pests dehydrate and die. Diatomaceous earth can also be ingested by dogs and help to remove internal parasites by scratching the lining of the digestive system and causing the parasites to be eliminated.

How often should I apply diatomaceous earth to my dog?

The frequency with which you apply diatomaceous earth to your dog largely depends on the specific problem you are trying to treat. Here are some guidelines:


If your dog has fleas, you should apply diatomaceous earth to their fur once a week until the fleas are gone. You can also sprinkle diatomaceous earth in your dog’s bedding and on carpets or other areas where fleas are likely to hide.


If your dog is prone to ticks, you can apply diatomaceous earth to their fur every two weeks to help prevent tick infestations. You should also check your dog for ticks regularly and remove them promptly if you find any.

Internal Parasites

If you’re using diatomaceous earth to help remove internal parasites, you should give your dog a tablespoon of food-grade diatomaceous earth once a day for ten days. After that, you can reduce the frequency to once a month.

General Health

If you’re using diatomaceous earth to improve your dog’s overall health and digestion, you can add a teaspoon of food-grade diatomaceous earth to their food once a day. Be sure to mix the diatomaceous earth well with the food and provide plenty of fresh water.

Is diatomaceous earth safe for dogs?

Diatomaceous earth is generally considered safe for dogs when used properly. It is non-toxic and does not contain any harmful chemicals. However, diatomaceous earth can be irritating to the lungs and skin, so it’s important to wear a mask when applying the powder and avoid getting it on your skin or in your eyes. Additionally, you should only use food-grade diatomaceous earth, as other forms may contain harmful additives.

Are there any side effects of using diatomaceous earth on dogs?

Some dogs may experience minor skin irritation when diatomaceous earth is first applied, but this usually goes away quickly. Additionally, dogs with respiratory issues may be more sensitive to the dust created by the powder, so it’s important to be cautious when using diatomaceous earth around these dogs.

What other benefits does diatomaceous earth offer for dogs?

Diatomaceous earth has many additional benefits for dogs, including improving coat health, reducing odor, and supporting digestive health. Its abrasive properties help to remove plaque and tartar from teeth, and it can also help to reduce symptoms of arthritis and other joint issues.


If you’re considering using diatomaceous earth to keep your dog healthy and free of pests, be sure to use food-grade diatomaceous earth and follow the guidelines for application based on your specific needs. With proper use, diatomaceous earth can be a safe and effective natural remedy for a variety of canine health issues.
