The sad thing is there is dominant behavior out there . . . but "Dominant" has just come to mean "poorly behaved," "doesn't know any better," "independent," "not a robot," and "bratty" as well as dominant. It is not a good catch all catagory, since you do not use the same solutions for all of the above problems (if they are problems at all). Basically, these days dominant=not doing precisely what the TRAINER things the dog should do (forget what the owner thinks). Its dangerous and stupid.
I liked my trainer, who refered to Sarama as "very Alpha." What she meant by that was that Sarama was behaving fine at that time, but I should expect some challange, considering how she related to other dogs. She didn't tell me to DO anything about it (Sarama just IS that way) but that if she does start breaking the rules that *I* set, I should not let her get away with it. Note, those are the rules that I set in my house, not an artifical set of rules supposed to assert my dominance. Sigh, but I suppose that's not 'catch-wordy' enough and too complex for most people to bother with . . . .
