 We talked about Nexgard Plus is a lot cheaper than Simparica. Well, yeah, there's Nexgard, which is just a flea and tick preventive, and then there's Nexgard Plus that has the heartworm preventive in it. I don't know. I haven't priced them out, so I don't know which is more expensive. But Nexgard used with a separate heartworm prevention like Interceptor or HeartGuard is quite often cheaper than the combo drugs like Nexgard Plus or Simparica Trio.
