New (to me) survey: Dog aggression and owner aggression

I posted not long ago about how Alpha rolling was both not my style and also not a safely recommended training technique. A study in 2009 by the University of Pennsylvania veterinary researchers linked an exacerbation of aggressive dog behavior with punitive and confrontational training techniques, entitled "Survey of the use and outcome of confrontational and non-confrontational training methods in client-owned dogs showing undesired behaviors" by Meghan E. Herron, Frances S. Shofer and Ilana R. Reisner. Basically, if you're aggressive your dog will be too. Of course, Patricia McConnell beat me to posting about the study, but in a way, I'm glad. She's somebody I've heard of, read a lot, and am confident recommending her advice to people.
