Frequently Asked Questions

Q1: Which is the safest heartworm prevention for dogs?

Ans: The safest option depends on your dog's individual health, breed, weight, and lifestyle. Heartgard Plus and Simparica Trio are among the most widely recommended heartworm preventives by veterinarians. Always consult your vet before starting any preventive, as certain breeds such as Collies may have sensitivities to specific ingredients.

Q2: Can puppies take heartworm medicine?

Ans: Yes, but the minimum age varies by product. Heartgard Plus is approved for puppies 6 weeks and older, while Simparica Trio is approved for puppies 8 weeks and older weighing at least 2.8 lbs. Always consult your veterinarian to confirm which product is appropriate for your puppy's age and weight.

Q3: How often should I give heartworm medication?

Ans: Heartworm preventives are given once a month, year-round, even in winter. Mosquitoes, which transmit heartworm larvae, can remain active in warmer indoor environments during colder months. Consistent, uninterrupted monthly dosing is the only way to ensure your pet stays fully protected throughout the year.

Q4: Does Simparica Trio also prevent fleas and ticks?

Ans: Yes. Simparica Trio for dogs is an all-in-one chewable that protects against fleas, ticks, heartworms, and intestinal worms including roundworms and hookworms. It is a prescription-only monthly chewable that simplifies parasite prevention for pet owners managing multiple protection needs in a single dose.

Q5: Where can I buy heartworm prevention for dogs?

Ans: You can order Heartgard Plus, Tri-Heart Plus, Simparica Trio, and more products from HardyPaw with fast shipping. Simply upload your valid prescription at checkout and our team will verify it quickly. All medications are sourced from licensed suppliers to ensure authenticity and quality for your pet.

Q6: What happens if I miss a dose of heartworm prevention?

Ans: If you miss a dose, give it as soon as you remember and resume the monthly schedule from that date. Missing a dose can leave your pet unprotected and potentially allow heartworm larvae to mature. Contact your veterinarian if multiple doses have been missed, as a heartworm test may be recommended before restarting prevention.
