I love Richard's Organic Pet Calm! I think it works great. I have a Newfoundland Puppy who was going through some serious anxiety after coming in to our home. So much so that he would vomit and cry all night, and would get the runs. But the Pet Calm helped him to relax and chill, he started to sleep through the night and was in a much better mood in the mornings, and my dog Quint love love love's the flavor of it. For me however I wish it came in a much larger bottle for my much larger dog, and was avalible in more stores.
Good luck
This is my dog at 14 weeks of age:
