Vectra 3D = sick dogs

My letter to Vectra....
I applied Vectra 3D to my Lhasa Apso and Chihuahua and both have had very bad reactions. My Lhasa Apso started running around digging into the couch and rolling around the carpet frantically. He kept scratching and pawing his face so I brought him into the tub and flushed his eyes out with cups of water. He continued to scratch himself like crazy and looked like he completely lost his mind. My Chihuahua also become extremely itchy and kept wining and crying for me to scratch her back. I bathed both of them in a oatmeal bath to try and sooth their skin but it did not work. I gave both of them benadryl and that didn't work. The next day I bought an anti itch medicated shampoo and bathed them again and gave them more benadryl. My Lhasa started to bite the air like if he was halucinating and his butt is extremely itchy and uncomfortable to the point he can barely walk without sitting down to try to itch it. When I take him for his walks he tries to roll around on the street gravel to relieve his itch its like he's trying to rip his skin off. I've never had this reaction from a flea medicine before and am so upset that my dogs are so uncomfortable. If they don't feel better tonight I will have to bring them to the vet tomorrow because I am very worried for their health. They are both very healthy and very well taken care of and this product you sell has poisoned my dog!
