Hat Tip to Lassie Get Help for posting an excellent video, put together by Pit Bull Guru, interviewing Jean Donaldson, Dr. Ian Dunbar and Dr. Nicholas Dodman.
I personally respect all of their opinions as experts in their field. It is a well put together video and should be circulated widely. What I particularly like about this video is the simplicity of it. They do not go into great detail but make some concrete statements that need to be said and understood.
