A lot of this. But then, on the other hand, I think there are still things too well-accepted in pockets of the dog community so maybe I'm too judgmental myself.This might sound like kind of a pretentious maybe even wankyanswer but here goes:
I wish that dog people could be more forgiving of other dog people. What I mean by that is ...well less cliquey and more accepting. We all have our opinions of how dogs should be treated, acquired, raised, trained, fed, ect. However I have noticed that a lot of dog people aren't particularly accepting of other peoples ideas. It seems if you don't do things "their way" then everything you do is wrong wrong wrong!
People cannot seem to accept that there is "No one true way".
