Is it safe to combine Bravecto and K9 Advantix II on my dog?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | neutered | 1 year and 7 months old | 65 lbs

I applied Bravecto on my lab mix on August 14 and it is supposed to last for 12 weeks. We moved and are finding that mosquitoes are terrible where we now live. On Oct 14, I would like to apply K9 Advantix II because it helps to repel mosquitoes too. Will this be a problem because Bravecto is still in his system until November? Thanks much. Angela

Bravecto and Advantix contain different drugs that work in different ways - it is safe to give the two together. You should also be sure that Zeke is on a heartworm preventative - this is the main disease in dogs that is spread through mosquitoes.
