As for the demise of the wolf pack theory - why do you think it has met it's demise? Possibly because it no longer bears relevance to the domesticated dog??
and caty, if you approve of methods like prong collars watch Cesar Milan - if you don't i think you should question his methods and how he achieves the dubious results he gets....
Wolf pack theeory met it's demise because learning moved on.
Dogs are not wolves and do not live in the same environment.
Over time both artificial and natural selection have changed the dog , it's appearance and behaviour from that of it's ancestor.
Man has bred dogs for various traits including tameness ,which has had the result of altering the dog in many ways.
Belayev, a russian scientist carried out an experriment on foxes In the 1950s that had astonishing results.
Some of the details below in an essay I wrote for college in my first year.
Dmitry Belyaev of the Soviet Union's Institute of Cytology and Genetics in Siberia began testing a hypothesis to look at whether selection for a behavioural trait—tamability—could bring with it the morphological and physiological traits associated with domestication. (Gilbert n.d)
Belyeav’s experiment provides a highly probable biological mechanism for the self-selection of wolves into dogs. (Coppinger, 2005 p.63)
The experiment began with 30 male foxes and 100 vixens from a commercial fur farm, which were bred with strict criteria for tameness.
(Gilbert n.d)
Tameness was measured by the ability for the foxes to behave in a friendly manner to their handlers, wagging their tales and whining.
(Coppinger, 2005 p.64)
The effects of artificially selecting for tameness brought about several changes in the behaviour and appearance of the foxes, which were noted by Belyaev. (Jackson, 2006 lecture notes 4)
These included: turned up tail, dropped ears, early sexual maturity, two breeding, cycles per year, coat colour, smaller jaw, teeth and skull size. (Morey1994)
The physical and behavioural features that tended to be retained were those associated with juveniles, a process called paedomorphosis. (Morey1994)
These changes took only 20 generations to achieve a fox that looked and acted like a dog. (Jackson, 2006 lecture notes 5)
This process however would have taken much longer in the wild as the selection criteria would not have been so specific.
(Jackson, 2006 lecture notes 5)
As man selectively bred his tame wolves, he effectively narrowed the gene pool, which led to more rapid changes in the dogs’ morphology, physiology and behaviour. (Jackson, 2006 lecture notes 5)
Dogs are not wolves so why expect the same behaviour and social structure to be the same.
Even the studies on wolves have been to a point misunderstood in the way the wolves were observed in a false and captive environment.
In my oppinion The leader of the pack theory gave credance to the fact that we could boss our dogs and punish them for not doing what we wanted.
There is no understanding of the dog and it's behaviours here, just our human interpretation.
As for Cesar Milan, in my oppinion you will learn more by switching off and picking up a book such as the culture clash.
