How to refill Heartgard Plus for my dog without a vet visit?

Handsome boy! Yes, he will need a prescription. Contact your vet; a heart worm test may be required first. Here's some great info on heart worm prevention and why routine testing is recommended: https://d3ft8sckhnqim2.cloudfront.net/images/Think_12_PDFs/Think12Dog_Dos_and_Donts101316.pdf?1476362471 Thanks for asking PetCoach!

You would need to see a veterinarian in person to establish a valid veterinary patient/client relationship for Lucy and to make sure she is healthy to start preventatives. You could make an appointment with a veterinarian near you, or you can also obtain this service (along with a heartworm test which would be required first) at Vetco vaccine clinics.

Tri-Heart is generic Heartgard and is just as effective. I am not sure why your vet won't prescribe it for you. You cannot buy any heartworm prevention over the counter so you will need a prescription. I suggest you bring your dog to one of the VETCO vaccine clinics at your local Petco stores (see schedule below). Bring proof of his last negative heartworm test and they can give you a prescription for the Tri-Heart. There is no charge for the exam. Just the cost of the medication. Hope this helps!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question. You need a script because the medication is prescription only. Even if you tried to buy the heartworm medication online, it still requires a script. Should you find heartworm medications that do not require a script, they are counterfeit. I hope this helps!

I do recommend monthly heartworm prevention starting at 8 weeks of age. It is a prescription so a veterinarian does not have to personally give the pill but you need to either buy it from a vet or get a prescription from a vet. The only medication that needed to be at a veterinarian's office is Pro-heart. This is an injectable heartworm prevention that lasts for 6 months. Thank you for using Petco Pet Education Center, formerly Petcoach.

You will need to go to a vet as it requires a negative heartworm test before it can be prescribed. This is a simple, fast blood-test that will let the vet know it is safe to start preventive medication. Why this is required is if your pet already has heartworms and is given the medication, it can kill the worms too quickly which can cause blockages of the blood vessels leading to potential stroke or death. Making sure your pet is negative first will ensure it is safe to administer.

You can submit a stool sample and deworm Miso every 3 months, or you can simply deworm him on the same schedule without submitting a stool sample. Discuss OTC and prescription dewormers with your veterinarian. Miso should still be on a flea and tick preventive as well.
