i read all Jan's books and thouroughly enjoyed them at the time, but then i broadened my horizons and learned about learning theory and wolfpack theory and it's demise.
I believe a lot of what Jan does works but not for the reasons she gives.
I tried some of her methods and look back at what a total Pratt i was eating before my dog and trying to make myself pack leader.
I too would recommend the culture clash to read as well as Dominance Fact or Fiction by Barry Eaton and Ray and Lorna coppinger's Dogs, A New Understanding of canine origin, Behaviour and evolution.
I would also reccomend How dogs learn by Burch and Bailey.
I do keep an open mind on all methods but unless Jan has come up with any new ideas then i 'm afraid she has nothing to offer me.
I am on a foundation degree in Canine Behaviour at the moment and her methods are less than popular there too.
