Is it safe to give Bravecto if Vectra 3D didn't work for my dog?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 11 years and 11 months old | 25.4 lbs

I used Vectra 3D on my dog 9 days ago, but I don’t think it worked. Is it safe to give him a Bravecto chew now?

These are different drugs and do not negatively interact, so it's OK to give the Bravecto, but it may be unnecessary. Sometimes owners will still see fleas and ticks on their dogs, but they are dead. I recommend checking to see if they are truly alive before giving the Bravecto. I also recommend reading the article at the link below it is fleas that you are treating. https://www.petcoach.co/article/5-tips-to-get-rid-of-fleas/ I hope that helps and all is well with Quincy.
