Excellent! just what I thought.

Whilst I cannot even begin to approach the level of scholarship of your post, it bears a distinct relation to the Dingo in Australia.

What happened with the Dingo is that they were introduced by Aboriginal Populations who arrived about 40 thousand years ago, but since then the Indigenous population has abandoned them as companion animals and they have become totally feral.

Since the European Invasion of the last two centuries old world dogs have interbred with the dingo but a few "wild" strains exist, particularly on uninhabited offshore large islands such as Fraser Island in Queensland where the strain is almost "pure". These dogs are almost identical to dogs found in south East Asia, in Thailand etc.

Until about 200 years ago, Australian Aborigines had no agriculture in the traditional sense, although they performed periodic "burn offs" of the bush to regenerate pastures for hunted animals.

The fact that they remained hunters and gatherers, whilst abandoning their previous (for whatever) relation with canids suggests that dogs were, to them, not useful in their hunting lifestyle.
