No matter what ideals humans have, and how hard they try to make dogs fit their ideals, there will always be dominance and submission in canine behaviour and social structure. That is nature, that is how animals have lived for thousands upon thousands of years, and no amount of wishful thinking will change that. To be honest, I can't stand these "dominance debunked" articles. After spending a little under 10 years observing wolf behaviour and an entire career in animal care, which included a few years working with large packs of dogs, I firmly stand by the fact that dogs indeed use dominance, submission and rank amongst each other.
Do I think many people misuse the term Alpha and do not properly understand what it means? Absolutely. It's a term that has been tarnished by the media, and by trendy trainers.
