What OTC flea treatment is safe for my diabetic dog on Sentinel?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 9 years and 2 months old | 35 lbs

My diabetic dog is currently on Sentinel for heartworm prevention, but I was wondering what kind of flea treatment would be best for her to use alongside it that I can purchase over the counter, so to speak. The fleas are bad this season!

Over the counter flea products that are fine to use with sentinel include frontline plus, advantage and Advantix. Just be sure to not bathe your dog a couple days before or after applying any of those products as that can affect how effective they are.
