I wanted to know what suggestion/tips that you may have for me to keep my dog calmer. For example, I attend a group training class that my Dog trainer has on the weekends. When we get out of the car Sadie is excited and pulling to get to the group. What is the best way to break this to have her walk more calmly to the group? Any specific videos or training tips for this? Once we get to the group she will settle after a few minutes and will work for me well. Thanks for the help.
