Bests & Worsts Reviews from Amazon

Our Australian Shepard developed severe itching and became very irritable after installing this Bayer Flea and tick collar. She started running into walls in our home and became very delirious. Contacted Bayer on their emergency telephone number on a Sunday afternoon and they were very helpful. Had to bath Zoey three times with Dawn detergent and remove the other collar off of Gabby, who had no reaction, but had the oil from the Bayer collar. Poor Gabby also had to be bathed three times with Dawn detergent. After three more days Zoey fully recovered. Be very careful with this collar. It put us through pure hell.
