The domestic dogs of some North American Indian tribes closely resemble the coyote; the black wolfdog of Florida resembles the black wolf of the same region; the sheepdogs of Europe and Asia resemble the wolves of those countries, whilst the pariah dog of India is closely similar to the Indian wolf.
The common or pariah dog is generally of sandy color; in Upper Egypt there is a breed of wiry rough-haired black dogs, noted for their fierceness.
In general appearance it is very like some of the pariah dogs of India and Egypt; and, except on distributional grounds, there is no reason for regarding it as specifically distinct from such breeds.
Consequently the Australian natives must be presumed to have reached the island-continent by way of Malaya; and if this be admitted, nothing is more likely than that they should have been accompanied by pariah dogs of the Indian type.
Confirmation of this is afforded by the occurrence in the mountains of Java of a pariah-like dog which has reverted to an almost completely wild condition; and likewise by the fact that the old voyagers met with dogs more or less similar to the dingo in New Guinea, New Zealand and the Solomon and certain other of the smaller Pacific islands.
On the whole, then, the most probable explanation of the case is that the dingo is an introduced species closely allied to the Indian pariah dog.
Their continued existence as a pariah class after the Exile would be a perpetual reminder of the dangers and degradation of the most popular Syrian creed.
