http://www.bachflower.com/index.html -- on the menu on the left is a section for pets.

It works, on humans and animals. I've always kept some at home and carry some in my purse. I never knew I could use it for pets until I spoke with an animal behaviorist and she suggested it to settle my newly adopted shelter dog. My children would take it for bumps and upsets, I'd take it if something upset me, etc. etc.
