Bad idea. Bad, bad, bad, idea. There is no way to monitor how a dog feels on a psychotropic medication. How would you like someone to give you something that effects your brain and be unable to tell them how weird or horrible it makes you feel? And you can't stop that person from continuing to give it to you. Did you plan to evaluate the effect on his brain by how much he wags his tail? For heaven's sake, don't do such a thing to your dog.
