Why is Canis familiaris labled as "introduced"?

[Italopithecus]

For example, we currently classify the domestic dog and domestic cat as “introduced” pretty much everywhere, but we don’t do that for other domesticated animals like domestic turkeys (which are listed as native in the U.S.). How should domesticated animals be handled?

If a species has been domesticated but it is also known as wild and it is sure that at least some wild populations have always been so (that is they have never been introduced in the past), there are two cases:

1. the domesticated animals belong to a different subspecies than the wild one. Then the domesticated subspecies is introduced.

2. the domesticated animals do not belong to a different subspecies than the wild one. The species is both wild and introduced. As far as iNaturalist is concerned it would be better to keep it as native.
