How to remove parasites from dogs' bodies

If you’ve noticed your 6-month-old Pug, Milo, scooting his rear on the carpet or vomiting up tiny white specks, parasites like worms or fleas might be to blame. When Milo had roundworms as a puppy, I was hesitant to use strong chemicals right away—so his vet helped me combine natural prevention with targeted care. For first-time U.S. dog owners, “natural” parasite control works best as a supplement (not a replacement) for vet-recommended treatments, focusing on repelling pests and supporting your dog’s body to fight infestations gently.

Parasites like fleas, ticks, and intestinal worms thrive on dogs with weak immune systems or exposure to contaminated environments (like grassy parks or shared dog runs). Natural methods work by either creating an environment parasites hate (e.g., certain herbs) or boosting your dog’s gut health to make them less hospitable to worms. Milo’s vet explained that while natural remedies won’t eliminate a severe infestation (like a heavy hookworm load), they’re great for prevention and mild cases. For example, diatomaceous earth (food-grade) dehydrates fleas by breaking their exoskeletons, and pumpkin seeds contain amino acids that paralyze small intestinal worms, making them easier to pass.

Start with prevention: Sprinkle food-grade diatomaceous earth on your dog’s bedding and carpet (let it sit 24 hours, then vacuum) to repel fleas—avoid the dusty kind, which irritates lungs. Add 1 teaspoon of ground pumpkin seeds to Milo’s kibble daily; he loved the nutty flavor and it helped keep his gut clear of tapeworms. For ticks, mix a few drops of cedarwood or lavender oil (diluted in water) in a spray bottle and mist his fur before walks—parasites hate these scents. For apartment dwellers, wash your dog’s bed weekly in hot water (130°F+) to kill flea eggs, and avoid communal water bowls at dog parks (a common source of worm eggs). Never use essential oils undiluted—they’re toxic to dogs’ skin and can cause seizures if ingested.

Never punish your dog for scooting or having accident from worms—this violates U.S. animal welfare norms and adds stress, which weakens their immune system. If you see signs of a severe infestation (bloody stool, weight loss, lethargy), call your vet immediately—natural methods aren’t enough for life-threatening parasites like heartworms. Stay compliant with local laws: Keep your dog’s rabies vaccine current (required nationwide) and always clean up their poop with gloves and a sealed bag—worm eggs spread through feces, and cities like Chicago fine up to $150 for not picking up. Use positive reinforcement (a treat after applying natural flea spray) to make parasite care stress-free.

Natural parasite control is safe, gentle, and effective for prevention. By combining herbs, gut support, and vet check-ups, you’ll keep your dog parasite-free without relying solely on harsh chemicals.
