Before You Buy
Key Buying Factors
01
Active Ingredients
Look for herbs like pumpkin seed, fennel, and garlic that support gut health and help expel worms. Avoid products with artificial preservatives.
02
Spectrum of Coverage
Some dewormers target specific worms like roundworms or tapeworms. Broad-spectrum formulas are better for prevention, while targeted ones may be needed for known infestations.
03
Form and Ease of Use
Dewormers come as liquids, powders, or capsules. Liquids are easy to mix with food, while powders can be sprinkled. Choose one that fits your dog's eating habits.
04
Safety and Side Effects
Natural doesn't mean risk-free. Some herbs can cause digestive upset. Check for well-tolerated formulas, especially for puppies or sensitive dogs.
05
Manufacturer Reputation
Choose brands that provide transparent sourcing and manufacturing practices. Look for companies that follow Good Manufacturing Practices (GMP).
06
Price per Dose
We avoided pricing in our guide, but consider the cost per treatment. Some products require a course over several days, increasing the overall expense.
Living With It
Care, Cost and Maintenance
Consult Your Vet First
Always get a fecal exam to confirm the type of worms. Natural dewormers may not kill all parasites, and some infections require prescription medication.
Follow Dosage Instructions
Overdosing on herbs can cause toxicity. Use the weight-based chart on the product and never exceed the recommended amount.
Repeat as Directed
Most natural dewormers need a second dose after 10-14 days to catch newly hatched worms. Mark your calendar to complete the full treatment.
Pro tip
To maximize effectiveness, give the dewormer on an empty stomach first thing in the morning, and mix with a small amount of pumpkin puree to mask the taste and boost gut health.
Frequently asked questions
Are natural dewormers safe for puppies?
Many herbal formulas are safe for puppies over 6 weeks old, but always check the label for age recommendations and consult your vet.
How often should I deworm my dog naturally?
For prevention, monthly use of a gentle herbal blend is common. For active infections, follow the product's treatment schedule, typically 3-7 days with a repeat.
Do natural dewormers kill all types of worms?
Most broad-spectrum formulas target roundworms, hookworms, and tapeworms, but may not be effective against whipworms or heartworms. Always match the product to the specific worm.
Can I use natural dewormer with prescription medication?
Generally yes, but it's best to separate by a few hours to avoid interaction. Consult your veterinarian for guidance on combining treatments.
What is the best way to administer liquid dewormer?
Use the included dropper or syringe to measure the dose, then mix with a small amount of wet food or broth. Some dogs will take it directly if flavored.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
