How long should I wait to give Bravecto after topical flea treatment?

Updated On September 23rd, 2025

Pet's info: Dog | Australian Shepherd | Male | neutered | 4 years and 6 months old | 88 lbs

We applied Heart topical flea treatment on my Australian shepherd last week but it doesn't seem to be working on the flea problem. We got him Bravecto today to see if that helps. Is it safe to give him the bravecto today since it's on been a week since we applied the topical?

Hello, sorry to hear about Brody. Bravecto has not been associated with any drug interactions, including any other topical flea medications. I would wait at least 2 weeks after your applied the Hearts medication before giving him the Bravecto. In addition to the extra flea preventative, you should also consider treating your environment for fleas. This includes washing bedding, vacuuming, and washing any clothing Brody may have direct contact with. This will hopefully reduce the flea burden in your environment to help you get control of the fleas. Only about 5% of the flea problem is what we see on our pets, the rest of the problem lies in our environment as eggs and immature life stages of fleas. When vacuuming, remember to not reuse the same vacuum bag. When spraying your environment with insecticide, remember to use products that are safe for pets and even then, if possible, remove them from the environment for 1-2 hours. Hope this helps and best of luck.
