Thank you for this. He's had only 3 doses and the side effects are taking over. I called the vet today to see what to do as he's thrown up everyday on it and has diarrhea, and the large animal vet said to stop it til I can talk to my vet Monday. I made an appointment with him Monday afternoon and will stop the pill. At this point I'm unsure if it's allergies or anxiety. A lot more needs to be done.
