I applied Sentry Pro FXC to my beautiful Weimaraner. Within 2 hours he became extremely hyper and visibly in pain. After touching him and then my face I felt a horrible burning sensation. I tried shampooing the product off him and called the Emergency Veterinary clinic as it was on the holiday week-end. They instructed me to immediately wash it off twice using Dawn dishsoap, which I quickly did. Several days later he has open sores on his back, a cough and lack of appetite. He had a second visit to the vet and got a shot and 3 prescriptions. The vet believes he will make a full recovery. However, I believe he may well have died if I had not gotten the product off so quickly! This product is deadly and should be pulled from the market immediately!!
