I can see how people get frustrated to point of wanting to use these methods, but with puppies I think a good stern no tends to work wonders.
I happen to think these TV shows are brilliant for showing how a problem dog can be changed, and they certainly do encourage people to put more effort into their dog, rather than just giving up on them. Unfortunately they also seem to create a lot of DIY dog behaviourists thinking the problems ingrained in their dogs can be solved in the quick time showed on the shows. I wouldn't dream of using these methods without proper advice knowing me I'd be the one person to balls it up lol
