Are Tri-Heart Plus & Simparica good, affordable heartworm & flea meds?

Updated On September 23rd, 2025

Pet's info: Dog | French Bulldog | Female | spayed | 9 months and 27 days old | 19 lbs

Would you recommend Tri-Heart Plus Chewable Tablets for heartworm and Simparica Chewable Tablets for fleas and ticks? I want to get the right brand, but I'm worried about the cost, and these were some of the cheapest I found.

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.
