"If you want to know what a man's like, take a good look at how he treats his inferiors, not his equals."
(Harry Potter and the Goblet of Fire - J.K. Rowling)
Rationale for the quote
I may not exactly consider dogs my inferior, but the statement holds true for the relationship of people and dogs. I would only trust people who treat their dogs well and with respect. For me personally, that does not mean you cannot use all humane training methods (including corrections). I think opinions matter significantly on what is the best way to train dogs and most trainers who stand firmly behind specific strategies can make a good case for them.
It does however mean that people owe it to their dogs to train them and care for them so that the dogs can enjoy their life to their fullest potential. For some dogs this could mean daily dog park visits, while for other dogs this would be hugely overwhelming and the respectful thing would be to choose quiet walks instead. I just wish all dog owners would try their best to provide for their canine partners - not that everyone is perfect, because neither am I. But Ryder, Storm and I try :)
