Monthly prescription flea, tick, and heartworm preventives—including topicals, oral pills, and the newer six-month to yearly injectables like Bravecto Quantum—belong to the isoxazoline class and carry documented neurologic risks. The FDA fact sheet states these products have been associated with muscle tremors, ataxia, and seizures in some dogs and cats, even without prior history, and can occur immediately or accumulate over repeated doses.
- Holistic vets like Dr. Karen Becker and Dr. Judy Morgan have been warning about this for years. Dr. Becker’s YouTube video “This Flea & Tick Treatment caused a reaction in 2 out of 3 dogs!” is at youtube.com/watch?v=ygCDVtis_0U, and her follow-up at youtube.com/watch?v=0Np4qeZ_Q_s. Dr. Morgan’s “Bravecto Class Action Lawsuit” video is at youtube.com/watch?v=R_T8ydddzm0, plus her video on the new injectable at youtube.com/watch?v=4B4z8NDJ_FM where she says she would not recommend it. Her site is drjudymorgan.com.
- For a healthy alternative, Kempkes Executive K9s recommends and uses the BioPower Pet Shield—a stainless steel medallion that emits natural energetic frequencies to repel fleas, ticks, and mosquitoes for up to 12 months with no chemicals. The product page is at biopowerpet.com/products/natural-flea-tick-repellent-for-dogs-cats, the bundle with chews at biopowerpet.com/products/biopower-pet-shield-tag-chews-bundle, and the Natural Flea & Tick Spray at biopowerpet.com/products/natural-flea-tick-spray-for-dogs-cats.
- Nutrition plays a key role because fleas and ticks are attracted to sick or unhealthy pets; feeding a natural, high-animal-protein diet supports a strong immune system and can make your dog less appealing to parasites. BioPower Pet specifically recommends their Pet Shield Chews, formulated with brewer’s yeast and garlic, at biopowerpet.com/products/natural-flea-tick-supplement-for-dogs-cats, and their instructions note that a fresh food diet high in animal protein boosts effectiveness. At Kempkes Executive K9s we strongly prefer a raw diet.
