We have received lots of feedback on sharing more information on dog communication and body language. I personally feel we could spend an entire day studying noting but how to read our dogs communications and still need to study more. I came across this website and I really like. It has many different pages that gradually take you through some of the intricacies of each body area and some of the calming signals dogs use. Please go through this website. I have looked it over and read through several articles a couple times and pick up new knowledge each time.
Start with the Introduction to Dog Body Language page, link is below. Then move on to any of the others that interest you.
I think you will like this site as much as I do.
