Nearly killed my dog
Not sure what exactly is wrong, but I notified Bayer, the manufacturer about this adverse effect. Bought a 6 pack, and he did fine with first 5 months. Sixth dose (always on first of month) he got lethargic, irritable, and partially paralyzed. Washed him immediately, and will never use again. I bought peppermint oil, and spray him with this diluted in water now. Never again ADVANTIX II
