Is it normal to find live ticks on my dog after Bravecto treatment?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 35 lbs

I give my dog Bravecto, but I still find ticks attached to him. Sometimes the ticks are dead, but sometimes they are alive. Should I be worried?

No you should not be worried, in order for Bravecto to kill ticks, the ticks have to attach and feed on the dog. After giving Bravecto, it distributes to the tissue fluids just under the skin. When fleas and ticks feed, they ingest Bravecto and die. Bravecto kills 100% of ticks on dogs within 12 hours so it would not be unusual to see some live ticks during the first 12 hours that they attach. Remember to give the medication every 12 weeks.
