Why did the Argentina gray fox become extinct?

The Argentina gray fox (Dusicyon avus) is not extinct. It is actually a common and widespread species found in Argentina, Chile, and parts of Bolivia and Paraguay.

It is possible you are thinking of a different animal or there may be a misunderstanding.

To help me clarify, could you please provide more context or information? For example:

* Where did you hear this information?

* Are you thinking of a specific subspecies of gray fox?

* Do you have any other details about the animal you are referring to?

Once I have more information, I can provide you with a more accurate answer.
