That's the thing though, it
does work with some dogs... it's not objective to generalize like that. With the newspaper, the trick is that the touch of the paper
quickly draws the dog's attention away from whatever it was doing, while the noise makes sure the dog doesn't confuse it for positive attention. Again, it's not supposed to hurt, it's more of an attention-getter for a stubborn dog that doesn't give a crap about being scolded. My dad's golden retriever would be a real terror if it weren't for the newspaper, that's all I know... she thought scolding was a good thing and would sit there and wag her tail at you with the happiest look on her face while you're saying "No Molly, no!" in the most assertive tone you can muster
.
A quick bop with the paper though and she'd go into "uh oh, I'm in trouble" mode.
With the 2nd statement in bold, you've descibed exactly why I would never, ever use physical punishment. There are other ways that involve as minimal effort with no detriment to the relationship.
As for the 1st statement in bold, there are ways to do this without being physically or emotionally "mean" to the dog.
I don't agree with it at all, just as I don't agree with the use of other physical or emotional "punishments" or "corrections" (as some people like to call them to make it sound better).
A good action must be reinforced with either a treat or a pleasant and happy, playful tone of voice. If a bad action is to occur, then either a distraction (in the form of a loud, sharp noise) to distract the dog away from what its doing, aswell as being a slightly unpleasant sound, and giving the dog a slight shock (it is sometimes necessary imo) will deter the dog from doing this again, so in future, it can feel confident that it is doing right
I'm afraid it's all too easy to "humanise" dogs, and imagine they learn from physical punishment. It's true they are unlikely to continually repeat behaviours that they get scared/beaten for, but is that the way we really want to play it?
The way forward in training is to ensure you don't set yourself up for that "fall" (ie having to use punishment). Work out
why your dog is carrying out the unwanted behaviour, and prevent it
before it happens (distractional work with clicker, Kong etc). A dog can easily work out a desired behaviour and creating an alternative through positive reinforcement (eg. clicker work) will help as they will soon learn that Mum/Dad likes that, I'll do that for a reward.
Barking is never about a dog wanting to wind people up. We could call it a "symptom", and what you need to work out is the cause, and rectify it. All you end up with when using punishment is a dog who tries to communicate an issue getting beaten/scared by it. It rarely works itself out using negative methods, as the root cause is never addressed. The best and kindest way to sort these problems is generally through ignoring the bad
regularly and repeatedly, never caving, and creating an alternative where the reward is too good to pass up (in the meantime trying to rectify what causes the barking). A dog's not stupid, it'll work out which behaviour pays best
