mmm..well i heard that from many a dog behaviour experts, including Jan Fennel...
And how do you "show" a dog how to be relaxed and "independent" at home if not by being a good pack leader, and the dog being a submissive pack member, clear (and all the happier for it) about his pack status?
But i suppose its not necessarily the only problem..

Yeah maybe he "identifies" more with male members of his pack and doesnt like this "male" pack splitting up..dunno!

Cheers anyway
