DiscountPetCare<\/strong>. If you are still confused, it\u2019s always best to talk to your veterinarian to keep your dog\u2019s life happy and healthy.<\/p>\n\n\n\nFrequently Asked Questions<\/h2>\n\n\n\nQ. Can I switch my dog from Heartgard Plus to Simparica TRIO?<\/h3>\n\n\n\n
A. <\/strong>Yes, this is a common switch and generally straightforward, but the timing is important. The new treatment should \u2013be given within one month of the last dose of the previous one to avoid a gap in heartworm protection. Talk to your veterinarian before switching.<\/p>\n\n\n\nQ. Does Simparica TRIO replace a separate flea and tick product?<\/h3>\n\n\n\n
A.<\/strong> Simparica TRIO already covers fleas and ticks in addition to intestinal worms and heartworms. So, many dogs may not need a separate flea and tick preventive. Your veterinarian would be the best person to consult for guidance.<\/p>\n\n\n\n Q. Does Heartgard Plus or Simparica TRIO treat an existing heartworm infection?<\/h3>\n\n\n\n
A.<\/strong> Both Heartgard Plus and Simparica TRIO only prevent heartworm disease; neither is effective against adult heartworms. Dogs should be tested for existing heartworm infection before starting a heartworm-prevention program. Moreover, heartworm-positive dogs require veterinary evaluation and appropriate treatment.<\/p>\n\n\n\nQ. Can I give my dog Heartgard Plus and Simparica TRIO at the same time?<\/h3>\n\n\n\n
A. <\/strong>Don’t combine them unless your veterinarian specifically recommends doing so. Giving Heartgard Plus and Simparica TRIO together usually means duplicating heartworm and intestinal worm protection unnecessarily, since both already cover those parasites.<\/p>\n","protected":false},"excerpt":{"rendered":"There are many heartworm preventatives available on the market.
