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!

Hello. This is fine to use. I would not recommend giving both of these on the same day. Give one on the first of the month & the second on the 15th so there are no drug interactions. Thanks for using Petco Pet Education Center, formerly Petcoach.

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!

For heat worm prevention, I recommend Heartgard Plus. You can get it via prescription from your vet. As for flea treatment, I recommend Advantage or Revolution. They are monthly spot on treatments and are excellent products. You can also get them from your vet's office. I would find a local vet for your dogs so you can get these medications. Good on you for getting this done!

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.
