We buy these for our two mini weiner dogs, who when we travel get a little bit anxious and it seems to calm them down just enough so that they are manageable. They don't mind eating them, in fact they gobble them down. It is not a magic pill and it doesnt make them behave like zombies but it takes enough of the edge off that they can at least get to sleep. I know for us whenver we have to go long distances in the car we use these without fail.
