Episode 13: What Flea & Tick Preventatives Actually Do Inside Your Dog

Flea and tick preventatives are some of the most commonly prescribed medications in veterinary medicine, but how do they actually work? In this episode, holistic dog health educator Bre Drake takes a closer look at the class of drugs behind popular products like Bravecto, NexGard, and Simparica. She explores how these medications function inside the body, how they’re tested for safety, and what dog owners should understand before using them. Bre also discusses the concept of cumulative toxic load in modern dogs and why parasite prevention doesn’t have to be an all-or-nothing conversation. This episode invites dog owners to step back from fear-based decision making and take a more informed look at the tradeoffs involved in protecting dogs from parasites.
