Why Use Internal & External Parasite Treatments?

Fleas, ticks, heartworms, and intestinal parasites don't just exhaust your pet; they can shorten its lifespan. This section explains why monthly parasite prevention is the most important part of your pet's care routine.

• Fleas and ticks transmit Lyme disease, ehrlichiosis, and tapeworms.
• Heartworm infections are life-threatening and expensive to treat.
• Intestinal worms cause digestive problems and nutritional deficiencies.
• Year-round prevention helps avoid infestations in the future.

Consistent use of parasite control products keeps your dog safer and healthier all year.

Frequently Asked Questions

Q1: What is the difference between Simparica Trio and NexGard?

Ans: Simparica Trio protects against fleas, ticks, heartworms, and intestinal worms in a single monthly chew. Standard NexGard controls fleas and ticks only, while NexGard Plus also covers intestinal worms. If your dog needs broader multi-parasite protection in one dose, Simparica Trio or NexGard Plus may be the more comprehensive option, depending on your vet's recommendation.

Q2: Do I need to get a prescription for Simparica Trio?

Ans: Yes, all heartworm preventives, including Simparica Trio chewables, are prescription-only medications. This comes down to the fact that a dog needs to test clear of heartworm before starting any preventive treatment, as giving it to an already-infected dog can cause serious complications. Your vet will check your dog over and issue a prescription once they are satisfied everything is in order. From there, you can upload it directly at HardyPaw's checkout and we will take care of the rest.

Q3: How often should I give parasite prevention?

Ans: Most parasite prevention products, including Simparica Trio and NexGard, are given once per month, year-round. Consistent dosing is essential because parasites like mosquitoes, which transmit heartworm, and ticks can remain active even in cooler months. Skipping doses creates gaps in protection that can allow infestations or infections to develop before the next dose is administered.

Q4: Is there an option for puppies?

Ans: Yes. Simparica Trio is approved for puppies 8 weeks and older weighing at least 2.8 lbs, while NexGard is approved for puppies 8 weeks and older weighing at least 4 lbs. Always confirm your puppy's age and weight before selecting a product, and consult your veterinarian to ensure the chosen chewable dog flea and tick treatment is appropriate for your puppy's specific needs.

Q5: Where can I buy these products online?

Ans: You can shop Simparica Trio, NexGard, Trifexis, and more from HardyPaw with secure checkout. All prescription products require a valid veterinary prescription, which can be uploaded easily during the ordering process. Our licensed pharmacy partners handle fulfillment to ensure you receive authentic, properly stored medications delivered quickly and safely to your door.

Q6: Can I use multiple parasite prevention products at the same time?

Ans: In some cases, veterinarians may recommend combining products for broader coverage, such as pairing a heartworm preventive with a separate flea and tick dog chewable. However, combining products without veterinary guidance can lead to ingredient overlap or adverse reactions. Always consult your veterinarian before using more than one parasite prevention product simultaneously to ensure safety and avoid unnecessary duplication.
