There is a theory about dogs, about how at some point some
wolves who were more mellow figured they’d hang by the dump and eat what humans
left over, and very quickly, in one generation, it bred out the wolf traits of
killing for food. And this had,
previously, been the wolf’s whole gig. This so severely disrupted the DNA that everything else fell drastically out of
whack, and resulted in mutations from the Dachshund to the Terrier to the Great Dane and Saint Bernard. None of which look like the same
animal as a wolf.
I like to image
this in a sudden bloom of dog families in which each member looks like a different
species. It must have been a ruff
time to be a dog. It must have been a weird thing for man and dog to go through
this. Maybe owning dogs changed us too? There is a
mechanism, if people who could get along with dogs were much fitter, that would
do it.
