Chamomile for spastic dog?

I used it when my dog was having separation anxiety problems when we would leave. (She dug holes in the carpet!)... I just bought the tea bags and cut one open and gave it to her 20-30 minutes before we left. She weighs 5 lbs though. I'm not sure on the ratio? You could maybe try one pack and see if that does the trick. I'm so happy we don't have trouble anymore! Good luck!
