We unfortunately didn’t do our research on this HORRIBLE brand before using the liquid flea medicine. We trusted that no product THIS UNSAFE would be on store shelves. Within 10 minutes after applying the meds in the correct dosage, our dog’s entire body had swollen to the point of being unrecognizable. By the time we reached the hospital, which thankfully was close, her tongue had swollen to a size that filled her entire mouth. WE ARE SO LUCKY to still have her today! BAN THIS BRAND!
