I was searching online to find a training centre/class near Chelmsford Essex. I have stumbled across some, but personal experiences and recommendations would be helpful. I am not in need of special training (aggression, etc), just general obedience. My boy knows the basics, but its hard to get him to listen to me in the presence of other dogs, and I thought it would be fun to do something like this with him... Suggestions? Thanks! :)

This one sounds fine all intructors are qualified.
