So in humans, a toddler crawling away to get at something shiny is trying to be dominant? And the mom, who goes and gets the baby and brings him back, does that to be the boss? Sorry, I don't buy it. I don't consider myself my dog's "Master," and I doubt that many of the trainers on this forum do either. I am the leader; she trusts me to guide her and keep her safe. But her purpose in life is not to "serve" me. I didn't get a dog because I want a "servant." I got a dog for companionship, to do activities with, to entertain me with her silliness. Not to serve me.
