Did anyone ever hear of this? I am trying one day a week at a doggie daycare for my youngest dog. Severe seperation anxiety. Vet suggested prozac, I am going to try a day away once a week and see how she does. As I was waiting in the reception area last week, a lady was filling out paper work to have her dog boarded. She said, "she is afraid of loud noises, thunderstorms, fireworks. I usually give her melatonin to calm her down" I piped up and said I didn't know you can give dogs melatonin. She said, Yep. I asked if it knocks the dog out, she said no. Just relaxes it a bit. She looked at my dog and suggested 1mg. and go from there. well, I took a 3 mg. tablet, cut it in half and gave it to her. Nothing. didn't slow her down, didn't make her sleep. Nothing.
