Dogs and cats who go outdoors should be protected with monthly medications against Ticks, Fleas, heartworm and other parasites more prevalent and common between the warmer months (especially between spring and fall, or March thorugh November) if not all year round 12 months. They should also receive annual heartworm antigen testing (with or without tick borne disease testing) to ensure they are negative carriers before staring any monthly heartworm prevention treatments. Always get approved oral and/or topical parasite preventative medications through your veterinarian for your pets safety and efficacy. These include SimparicaTRIO, NexgardSPECTRA, Revolution, RevolutionPLUS, Advantage-Multi, Nexgard, Simparica, and other veterinary-approved medications, depending on your veterinarians recommendations for your individual pet.
