Your furry friend must have a current heartworm test result on file with your veterinarian in order to be prescribed heartworm medication. Please visit your veterinarian to have this test performed annually to protect your four-legged friend. Interceptor flavor tabs are a monthly, broad-spectrum parasiticide prescribed by your vet to help prevent heartworm disease. Plus, it treats and controls adult roundworm, adult hookworm, adult whipworm and adult tapeworm. It comes in a tasty tablet form, so you can give it to your pet as a tasty treat, or add it to her food for a boost of flavor.


For prevention of heartworm disease and the removal of adult roundworm and hookworm infections.

  • Always works for us

    By on

    We've been using Interceptor for a couple months now and it has kept our pup parasite free! Minus fleas and ticks that is, we use Simparica for that. We love the coverage that Interceptor has, doing everything but the above mentioned and tape worms which come from infected fleas. We used interceptor plus (which does cover tapes) the previous year but unfortunately my pup is allergic to chicken so can no longer have that added protection. She has never had any parasites while on this method of prevention though!

  • The pills are hidden in a chewable coating my dogs like

    By on

    I'm assuming that these pills work as my dogs have not been ill. But I'm very skeptical about preventative allopathic medicines. I am only following my Vet's strong recommendations. These pills are great, however, because the dogs easily swallow them in their edible coating.

  • Works as intended

    By on

    The medicine was easy to order and came in a good amount of time. My dog took the medicine easily and has not shown any negative effects. Overall pleased with the purchase. Chewy's prices are a little less expensive than competitors.

  • No chicken!

    By on

    So glad this formula is not made with chicken, but artificial beef flavor made from pork! My poor Aussie has allergies and is severly allergic to chicken.
