I applied this to my 6 month old dog and it almost killed her. She foamed at mouth, threw up, pooped all over herself. Had to take her to VET and have shots for reaction. Expensive VET bill, for something they recommended. It may kill fleas and ticks, but it almost killed my dog! I think this product should be removed from the market... It is to new for VETS to be recommending. I am going to ask my VET not to sell this product ever again! Dogs are our family and you do not want to hurt your animal. read full review »
