A recent peer-reviewed paper found owners reported flea & tick products🦟 using the potent pesticide, Isoxazoline💦, cause a reaction in 2 OUT OF 3 DOGS! Reactions include seizures, behavioural issues, muscular/balance issues, and even death.

The pesticide can be found in products like: NEXGARD, NEXGARD SPECTRA, BRAVECTO, SIMPARICA, CREDELIO, REVOLUTION PLUS, and others.

This pesticide is so powerfully potent🔥 that it starts killing within two hours after administration! In fact, it kills 98.7% of newly arriving fleas within 24 hours! Because of this, Isoxazoline drugs now carry a warning⚠️ on their labels in both the U.S. and Canada. 

Even the FDA-U.S. Food and Drug Administration has issued a warning statement for veterinarians and pet parents.
