Diatomaceous earth (DE) is a naturally occurring substance made from the fossilized remains of tiny aquatic organisms called diatoms. Its popularity has surged in recent years, touted as a natural alternative to conventional pesticides and dewormers. But with its increasing use around the home and garden, pet owners are naturally asking: is diatomaceous earth safe for dogs?
This article dives deep into the world of diatomaceous earth, exploring its different types, potential benefits, risks, and providing practical guidance on how to use it safely around your canine companion.
Understanding Diatomaceous Earth
To understand whether diatomaceous earth is safe for dogs, it’s essential to grasp what it is and the different types available. Not all DE is created equal, and the type you choose significantly impacts its safety.
What is Diatomaceous Earth?
Diatomaceous earth is essentially a powder composed of silica. This silica originates from the cell walls of diatoms, microscopic algae that live in oceans, lakes, and soils. Over millions of years, these diatoms accumulate in sediment, forming deposits that are then mined and processed into the fine powder we know as diatomaceous earth.
The sharp, microscopic edges of the diatom remains are what give DE its insecticidal properties. These edges can pierce the exoskeletons of insects, causing them to dehydrate and die.
Types of Diatomaceous Earth: Food Grade vs. Filter Grade
The most crucial distinction to understand is between food grade and filter grade diatomaceous earth. Food grade DE is considered safe for consumption by humans and animals, while filter grade DE is used in industrial applications and is not safe for ingestion.
-
Food Grade Diatomaceous Earth: This type has been purified and processed to remove impurities and reduce the crystalline silica content, making it suitable for use in animal feed and as a natural insecticide around the home. Look for products specifically labeled as “food grade” when considering using DE for your dog.
-
Filter Grade Diatomaceous Earth: This type is heated to very high temperatures during processing, which converts the amorphous silica into crystalline silica. Crystalline silica is a known carcinogen and can cause serious lung damage if inhaled. Filter grade DE is used in swimming pool filters and other industrial applications and should never be used around pets or humans.
Always double-check the label to ensure you are purchasing food grade diatomaceous earth. This is the only type considered safe for use around dogs and other animals.
How Diatomaceous Earth Works
Diatomaceous earth works through a physical, rather than chemical, action. The sharp edges of the diatom remains act like tiny shards of glass, abrading the outer layer of insects. This abrasion causes the insects to lose moisture and eventually die from dehydration.
For internal parasites, the mechanism is similar. DE is thought to damage the parasites’ outer coating, leading to their dehydration and elimination from the body.
It’s important to note that DE is most effective in dry environments. When wet, its abrasive properties are diminished.
Potential Benefits of Diatomaceous Earth for Dogs
When used correctly, food grade diatomaceous earth may offer some potential benefits for dogs. However, it’s crucial to remember that scientific research supporting these claims is limited, and DE should not be considered a replacement for conventional veterinary care.
Internal Parasite Control
One of the most common reasons people use DE for their dogs is to control internal parasites like roundworms, hookworms, and whipworms. The idea is that the sharp edges of the DE particles damage the parasites’ outer layers, leading to their dehydration and death.
While anecdotal evidence suggests DE can be effective against internal parasites, scientific studies have yielded mixed results. Some studies have shown a reduction in parasite load, while others have found no significant effect.
If you suspect your dog has internal parasites, it’s essential to consult with your veterinarian for proper diagnosis and treatment. DE may be used as a complementary therapy, but it should not replace conventional deworming medications.
External Parasite Control
Diatomaceous earth can also be used to control external parasites like fleas, ticks, and mites. When applied to the dog’s coat or bedding, the DE particles can damage the exoskeleton of these parasites, causing them to dehydrate and die.
DE is most effective against fleas in the larval stage, as the larvae are more susceptible to dehydration. It can be used to treat carpets, furniture, and outdoor areas where fleas may be present.
For ticks, DE can help to kill ticks on contact, but it’s not a repellent. It’s essential to check your dog regularly for ticks and remove them promptly.
Other Potential Benefits
Some people believe that DE can also offer other benefits for dogs, such as improving digestion, promoting healthier skin and coat, and boosting the immune system. However, there is limited scientific evidence to support these claims.
Risks and Precautions When Using Diatomaceous Earth for Dogs
While food grade diatomaceous earth is generally considered safe for dogs when used correctly, there are still some risks and precautions to be aware of.
Respiratory Irritation
The most significant risk associated with using DE is respiratory irritation. The fine powder can easily become airborne and inhaled, causing coughing, sneezing, and difficulty breathing. This is especially true when applying DE to your dog’s coat or in enclosed spaces.
To minimize the risk of respiratory irritation, always wear a mask when handling DE. Apply it carefully to avoid creating dust clouds. Ensure your dog is in a well-ventilated area during application.
Eye Irritation
Diatomaceous earth can also cause eye irritation if it comes into contact with the eyes. The sharp particles can scratch the cornea and cause discomfort, redness, and watering.
Avoid getting DE in your dog’s eyes during application. If DE does get in the eyes, flush them thoroughly with water.
Skin Irritation
In some cases, DE can cause skin irritation, especially in dogs with sensitive skin. The abrasive nature of the DE particles can dry out the skin and cause itching, redness, and inflammation.
If your dog develops skin irritation after using DE, discontinue use and consult with your veterinarian. You may need to moisturize the affected area to relieve dryness and itching.
Internal Consumption Risks
While food grade DE is considered safe for ingestion, consuming large amounts can cause gastrointestinal upset. Symptoms may include vomiting, diarrhea, and abdominal pain.
Follow recommended dosage guidelines carefully when administering DE internally. Start with a small dose and gradually increase it as needed. If your dog develops any gastrointestinal symptoms, reduce the dose or discontinue use.
Not a Substitute for Veterinary Care
It’s crucial to remember that diatomaceous earth is not a substitute for veterinary care. If your dog is sick or has a parasite infestation, you should always consult with your veterinarian for proper diagnosis and treatment.
DE may be used as a complementary therapy, but it should not replace conventional medications or treatments prescribed by your veterinarian.

What exactly is Diatomaceous Earth and what are its main uses?
Diatomaceous Earth (DE) is a naturally occurring, siliceous sedimentary rock composed of fossilized remains of diatoms, a type of hard-shelled algae. These microscopic remains are primarily made of silica, a compound found abundantly in nature. There are two main grades: food-grade and filter-grade. Only food-grade DE is considered safe for consumption.
Its primary uses are diverse, ranging from insecticide and filtration to a dietary supplement. In agriculture, it’s used to control insects in crops and livestock. Industrially, it’s used in filtration processes for beverages, swimming pools, and even in cosmetics. For pets, particularly dogs, food-grade DE is sometimes used as a natural dewormer and to control external parasites.
Is all Diatomaceous Earth the same? Which type is safe for dogs?
No, not all Diatomaceous Earth is created equal. There are two main types: food-grade and filter-grade (also known as pool-grade). The key difference lies in their silica content and processing methods. Filter-grade DE is heat-treated (calcined), making the silica crystalline, which is harmful if inhaled.
Only food-grade Diatomaceous Earth is considered safe for dogs. This type contains a very low percentage of crystalline silica (typically less than 1%), whereas filter-grade DE can contain a much higher percentage. Always ensure you are using food-grade DE specifically labeled for animal use when treating your dog.
How can Diatomaceous Earth benefit my dog?
Food-grade Diatomaceous Earth is believed to offer several potential benefits for dogs, primarily related to parasite control. Some pet owners use it as a natural dewormer, claiming it can help eliminate intestinal parasites like roundworms, hookworms, and whipworms by damaging their exoskeletons. Others use it topically to control fleas, ticks, and mites.
Beyond parasite control, some believe that DE can improve coat health due to its silica content, potentially leading to a shinier and healthier coat. It’s also sometimes suggested as a supplement to support joint health and overall well-being, although scientific evidence to support these claims is limited. Always consult your veterinarian before using DE for any health-related reason.
How do I safely administer Diatomaceous Earth to my dog?
When administering food-grade Diatomaceous Earth to your dog internally, the recommended dosage varies based on the dog’s size. A general guideline is approximately one teaspoon per day for small dogs (under 25 lbs), one tablespoon per day for medium-sized dogs (25-50 lbs), and two tablespoons per day for large dogs (over 50 lbs). It can be mixed into their food.
For topical application to control fleas or ticks, gently rub the DE into your dog’s fur, avoiding the eyes and nose. It’s best to do this outdoors or in a well-ventilated area to minimize dust inhalation. Repeat every few days as needed. Remember to always observe your dog for any signs of adverse reactions, and discontinue use if irritation occurs.
What are the potential risks and side effects of using Diatomaceous Earth on dogs?
While generally considered safe, Diatomaceous Earth does pose some potential risks. The most common risk is respiratory irritation from inhaling the fine powder. This can cause coughing, sneezing, and in some cases, more severe respiratory issues, particularly in dogs with pre-existing respiratory conditions.
Other potential side effects include skin irritation or dryness when used topically. In rare cases, some dogs may experience gastrointestinal upset if they are sensitive to DE. It’s crucial to introduce DE gradually and monitor your dog for any adverse reactions. Always use food-grade DE and avoid inhaling the dust.
Can Diatomaceous Earth replace traditional deworming medications from the vet?
No, Diatomaceous Earth should not be considered a replacement for traditional deworming medications prescribed by your veterinarian. While some anecdotal evidence suggests it may help control certain parasites, its effectiveness has not been definitively proven in scientific studies. Traditional dewormers are specifically formulated and tested to effectively eliminate parasites.
Relying solely on Diatomaceous Earth for parasite control could lead to a worsening of your dog’s condition if the parasites are not effectively eliminated. Always consult your veterinarian for a proper diagnosis and treatment plan for parasites. DE might be used as a complementary treatment in some cases, but only under veterinary guidance.
Where can I purchase safe Diatomaceous Earth for my dog and what should I look for on the label?
Safe Diatomaceous Earth for dogs can be purchased at many pet supply stores, farm supply stores, and online retailers.
