The Difference Between Parasites and Intestinal Worms
Parasites are fascinating and diverse organisms that live on or in another organism, known as the host, deriving nutrients at the host's expense. In this blog post, we'll delve into the world of parasites, exploring the differences between parasites in general and a specific subgroup known as intestinal worms.
What’s the Difference?
Understanding Parasites in Dogs: More Than Just Worms
The word parasite covers far more than just the worms you might see in stool. It’s an umbrella term that includes:
Protozoa (like Giardia and Coccidia)
Helminths (worms, including roundworms and hookworms)
Fungi and certain bacteria that thrive off a weakened host
Parasites are incredibly adaptive. They survive by feeding off their host’s nutrients, often without being seen.
Intestinal Worms: Just One Piece of the Puzzle
Intestinal worms are one subgroup of parasites — and while they’re the most familiar (because we sometimes see them expelled), they’re far from the only threat. These include:
Roundworms
Tapeworms
Hookworms
Whipworms
Pinworms (less common in dogs)
Each of these has a different life cycle, target organ, and impact on your dog’s health.
Where Can Parasites Live in a Dog’s Body?
Short answer: almost anywhere.
Digestive tract – Common worms, Giardia, Coccidia
Bloodstream – Heartworm, Babesia
Liver & gallbladder – Liver flukes, contributing to liver congestion
Lungs – Lung flukes or larvae causing chronic cough
Nervous system – Rare but possible with protozoa like Toxoplasma
Skin – Mites and burrowing parasites
Muscles & tissues – Encysted parasites (e.g., Trichinella)
This is why stool testing alone doesn't always show the whole picture.
Symptoms of Parasites in Dogs
Symptoms vary depending on where the parasite lives, the type, and how heavy the burden is. Common signs include:
Digestive troubles – Gas, diarrhea, vomiting, bloating, constipation
Nutrient deficiencies – Poor coat, low energy, picky eating
Weight loss – Despite a healthy appetite
Anemia – From blood-feeding worms like hookworms
Respiratory issues – Coughing, wheezing, or nasal discharge
Skin conditions – Chronic itching, rashes, or hot spots
Neurological symptoms – Shaking, seizures, or disorientation
Weakened immunity – Chronic infections or poor healing
“It’s important to note that parasites are not often considered in the above conditions, or even when no specific resolution to a condition can be identified. If you’re struggling to heal your dog — consider the possibility of parasites.”
Diagnosing Parasitic Infections
Diagnosis can be straightforward — or frustrating — depending on the type of parasite.
Stool analysis – Best for intestinal worms and protozoa, but may require multiple samples
Bloodwork – For heartworms, tick-borne blood parasites, and immune response markers
Live Blood Analysis – Ask me how to access this through a trusted peer
Imaging (ultrasound, MRI) – For flukes or cysts in organs
Biopsy or aspiration – For tissue-invading parasites
Symptom + history review – Still one of the most useful tools in our toolbox
Holistic Ways to Support Parasite Cleansing in Dogs
Because some parasites don’t live in the digestive tract, they won’t always show up in poop — and they may not respond to common worming meds. This is where a holistic approach shines.
Here are some foundational tools you can start with:
Apple Cider Vinegar (ACV) – Helps shift gut pH to discourage parasites.
Food-Grade Diatomaceous Earth (DE) – Micro-shards that may disrupt worm integrity in the gut.
Raw Pumpkin Seeds – Natural compounds may help paralyze intestinal worms.
Coconut Oil – Lauric acid supports immune defense and gut health.
Turmeric – Anti-inflammatory and may support immune response.
Garlic (in small, safe amounts) – May support gut cleansing when used properly.
Probiotics – Healthy gut flora can reduce parasite survival.
Essential oils – Fennel, ginger, Roman chamomile, and clove are just a few I may recommend (with proper dilution and fat pairing).
Herbal blends – Often include black walnut, wormwood, and other bitter herbs (these require cycling and vet or coach supervision).
Want to know the full protocol I use with my own dogs (and myself)? It's available in the client forum and includes advanced tools like binders, Raindrop sessions, and essential oil blends.
What About Ivermectin?
Yes, ivermectin is used for heartworm control — and it does work on some parasites. But it doesn’t eliminate all types (like tapeworms or liver flukes), and it doesn’t detox what’s already embedded in tissues. That’s where nutritional, herbal, and energetic support are crucial.
Why I Recommend Seasonal Parasite Cleansing
I suggest a minimum of two seasonal cleanses per year — Spring and Fall. These coincide with seasonal shifts, immune stress, and increased exposure (think: soil, water, fleas, ticks, and wildlife).
It’s not just about deworming... it’s about restoring balance.
Dana’s Thoughts
Parasites aren’t just a “poop problem.” They can disrupt your dog’s digestion, skin health, behavior, and even neurological function. Supporting your dog’s natural detox pathways, feeding a species-appropriate diet, and doing seasonal wellness cleanses can go a long way.
Some dogs need deeper support. If your pup has chronic skin issues, bloating, anxiety, or food sensitivities — parasites might be part of the puzzle.
