How to buy Interceptor Plus for multiple dogs without a vet visit?

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!

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 have all these done at a VetCo clinic. Here is a price list: https://www.vetcoclinics.com/services-and-clinics/vaccination-packages-and-prices/ and here are locations and schedules: https://www.vetcoclinics.com/services-and-clinics/clinic-locations-and-schedules/

You can get a heartworm test at any of our Petco/VETCO clinics. Here is a link to a schedule of the ones in your area based on the zip code you provided. ( https://www.vetcoclinics.com/services-and-clinics/clinic-locations-and-schedules/?zip=07013 )

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! The heartworm preventatives typically do require a prescription from your veterinarian which may require an exam initially if this is Annie's first time visiting her veterinarian. There are some over the counter flea preventatives such as Advantix and Advantage or Frontline. However, these may not work as well as prescription flea preventatives from a veterinarian. There are no over the counter heartworm preventatives- this does require a prescription with Annie's veterinarian. I hope this helps!

Yes, you can give both products at the same time and Charlie will likely do fine. If you want to be extra cautious, separate them by two days. Neither product had activity against ticks. If ticks are a concern where you live, you can switch the products to something like Simparica for fleas and ticks and the Interceptor for heartworms and intestinal worms. There’s not really a reason to use three different products. I hope this is helpful and please feel free to post any additional questions.
