Over the years, I've had a lot of conversations with others about the necessity, or lack thereof, of punishing dogs. On the forum lately, at least one poster complained that her dog "attacked" her, after being punished (don't know what kind of punishment, but assume it's physical if a ten month old pup has to use his teeth to fend off his owner).
I can't help but wonder why people who do this are so anxious to continue, even to the point of the dog retaliating. Clearly, the punishments have not worked, or the dog would no longer be pee'ing in the living room or raiding the trash. So, why is it that people get so defensive over the need to punish? Must be the dog's fault - maybe the dog has a screw loose - had forty gazillion dogs in my life, and none of them were this bad..... No, of course they weren't. But, it seems to me that the other dogs were probably of a less independent breed, or less confident individuals. They probably cowered or shut down, and never attempted to bite. So, was the owner a great owner then? Or, was the owner still just ignorantly abusing dogs by expecting them to know things that were never properly taught to them in the first place? What I see is that the person finally got a dog that didn't get it - and perceived the punishment as unfair. Dogs hate unfair.
At any rate, I vote for NOT continuing the same tactics and expecting different results. According to Einstein, that is the definition of insanity. For god's sake, if punishment doesn't work, stop defending it and try rewarding what you do want.
